OPINION
GRABER, Circuit Judge:
Plaintiff Kesner Liberal sued the City of Menlo Park (“City”) and seven of its police officers, individually and in their official capacities, under 42 U.S.C. § 1983, for violations of his civil rights arising from a traffic stop and subsequent events. He also brought several claims under California law against the City and its officers. Defendants filed a motion for summary judgment, asserting federal qualified immunity and state statutory immunity. The district court denied several officers’ claims of qualified immunity on Plaintiffs § 1983 claims. With regard to the state-law claims, the district court denied the City and several officers state statutory immunity. The individual officer-defendants filed this interlocutory appeal. We dismiss in part, affirm in part, and remand.
FACTUAL BACKGROUND
A. The Initial Traffic Stop
On an October night in 2005, at about 1:40 a.m., Plaintiff, an African-American *1068male, was acting as the designated driver for two friends after a night out. His passengers were Keith Hamilton, who also is African-American, and Tony Martinez, who is Mexican-Ameriean. Plaintiff testified that his front driver- and passenger-side windows were not tinted and that they were rolled down and therefore not visible.1 His rear driver- and passenger-side windows and rear windshield had a reflective tint. Traffic was light, and Plaintiff was obeying all traffic laws as he traveled north at approximately 30 miles per hour on El Camino Real, an arterial road in Menlo Park, California.
Officer Estrada was on duty in his patrol car. He was stopped at a red light in the southbound left-turn lane of El Camino Real. Plaintiff testified that Officer Estrada could see into Plaintiffs car through the rolled-down front window because, as Plaintiff passed the police car, the officer “follow[ed] [him] with his eyes.”
As Plaintiff continued north, Officer Estrada turned on the lights of his patrol car, but not its siren, and made a U-turn through the red light to follow Plaintiff. Not knowing whether the officer was attempting to pull over his car, but suspecting that he might be, Plaintiff made a right turn at the next light while the officer was approximately 300 feet behind him. Then, almost immediately, Plaintiff made a left turn into an unlit parking lot behind a walk-up burger stand. He parked near a dumpster and turned off his headlights. Officer Estrada followed Plaintiffs car into the parking lot at high speed. The officer parked behind Plaintiff and shined his spotlight at the car.
Officer Estrada testified that he was “agitated,” “a little pumped up,” and “a little scared” as he approached Plaintiffs car with his hand on his gun. He ordered Plaintiff and his passengers to put their hands up and out of the windows of the car. They complied. Officer Estrada then requested Plaintiffs driver’s license and registration, which Plaintiff provided. Plaintiff asked why he had been pulled over. In response, Officer Estrada accused Plaintiff of trying to flee, which Plaintiff denied.
The police dispatch logs show that Officer Estrada reported making this traffic stop at 1:43 a.m. Within one minute of that time, he asked for a DMV check on Plaintiffs license plate, called in Plaintiffs driver’s license and date of birth, reported that three subjects were trying to flee, and requested backup, which was dispatched immediately. Officer Keegan, the first backup officer to arrive on the scene, was there by 1:44:47 a.m. Officer Keegan testified that Plaintiff was “verbally confrontational,” making statements such as, “You stopped me for no reason.” Over the next several minutes, Officers Ayres, Romero, Tassio, and Wheaton, and Sergeant Prickett — essentially the entire Menlo Park Police watch — arrived on the scene.
B. Plaintiff and Martinez Are Handcuffed
Throughout the stop, Tony Martinez had been sitting in the right rear passenger *1069seat, talking on his cell phone. After running Plaintiffs information, Officer Estrada approached the rear passenger window and began yelling at Martinez to get off the phone.
At that point, Officer Estrada, Officer Keegan, or both, ordered Plaintiff to get out of his car. There is some uncertainty as to which officer handcuffed Plaintiff or whether one assisted the other. As Plaintiff began to step out of the car, an officer grabbed him by the wrist, pulled him out of the car, spun him around, and pushed him against the rear door of the car. Plaintiff was shoved against the door with enough force to rock the car, but the impact did not “knock [his] breath away.” He was then handcuffed and led to sit on the front bumper of Officer Keegan’s police car. Officer Estrada asked Martinez to get out of the car, handcuffed Martinez, and sat him on the trunk of Plaintiffs car.
C. The Tape Recording
Officer Estrada continued to yell at Martinez and Plaintiff, demanding to know why they had tried to flee. At that point, Plaintiff made comments to the effect that the traffic stop constituted harassment because of his race, that Martinez did not have to answer Officer Estrada’s questions, and that Plaintiff was going to contact his lawyer. Officer Keegan then pulled out an audio recorder, showed it to Plaintiff, and began recording.
The audio recording reveals that Officer Keegan partially Mirandized Plaintiff, telling him that “everything you say can and will be used against you in a court of law.” Plaintiff believed at that time that he was under arrest. Officer Estrada, not knowing that the conversation was being recorded, returned to speak to Plaintiff:
[Officer Estrada]: Here’s the deal, ok? This is the way I do business, ok. If you would have pulled over and not tried to ditch me [inaudible], ok, then you and I would have been having a more decent conversation, ok. But you tried to ditch me, I get behind you, and then you start shooting off your mouth to me, and then your friends are joining along. I got to make a decision here.
[Plaintiff]: Um.
[Officer Estrada]: Let me finish.
[Plaintiff]: Yeah, I, that’s why I [inaudible] I thought you was done sir.
[Officer Estrada]: Don’t interrupt. I need to make, I need to make a decision here. I’m going to decide whether I’m going to let three little punks walk all over me, and the reason I call you punks is you’re acting that way. I[’m] gonna have to decide whether I’m going to let three little punks walk all over me or whether or not to sit on you real fast and let you know that I’m the one in charge here, not you, ok. You understand me? Now, let me explain something else to you too. You may be able to get away with smarting off to some of the younger cops, you’re not going to do that with me and I’ll explain to you why, ok. Because, since I had no desire to become sergeant, I really don’t give a rat’s ass who I piss off. I don’t care about complaints.
[Plaintiff]: I know you don’t care I can see that.
[Officer Estrada]: Ok, so, so, so, it’s a lot of things in that Penal Code that I could arrest you right now for if I wanted to, so if I was you, I would just keep your mouth shut, don’t try to, don’t try to get smart with me, and we might have a better evening, you understand me? Do you understand me?
The audio recording captured Officer Estrada repeatedly accusing Plaintiff of trying to “ditch” him and of lying about it. Plaintiff denied the officer’s accusations *1070and claimed that he had made the right turn off El Camino Real, before he realized that Officer Estrada was trying to pull him over, because that was the way to his friend’s house.
The tape also captures Officer Estrada uncuffing Plaintiff after requiring Plaintiff to answer verbatim that he would “remain a gentleman.” Plaintiff estimates that he was handcuffed for approximately 25 to 30 minutes during the 45-minute stop.
At one point, Sergeant Prickett told Plaintiff that he was “just being damn right ignorant” by pulling over into a darkened alley. Sergeant Prickett continued, “1 mean stop, stop on the road because if this officer is not sure what’s going on and you do something stupid once he comes up on you, it’s very easy to get shot, you know, his safety is in jeopardy. Really, especially, you know, doing the whole routine back here.”
D. The Search of Plaintiffs Car
Plaintiff saw up to six officers searching the area around his car, including the nearby dumpster. He concluded that they were looking for drugs. After uncuffing Plaintiff, Officer Estrada grabbed Plaintiff by the arm, led him to his car, and asked him whether he owned the car and whether the officers could search it. Plaintiff answered “yes” to both questions. Plaintiff was then put, uncuffed, into the back seat of an officer’s patrol car while his car was searched.
Officer Estrada and other officers searched Plaintiffs car thoroughly, “turn[ing] everything upside down.” The search uncovered only a lawfully possessed, unloaded pellet handgun. The discovery of the pellet gun appears to have resulted in having the second passenger, Hamilton, handcuffed for about five minutes.
E. The Sobriety Tests and Line-Up
Throughout the stop, Officers Keegan and Estrada questioned Plaintiff about how much alcohol he had consumed that night. He answered that he “had probably two beers.” Officer Estrada administered two nystagmus tests to Plaintiff and determined that he was not intoxicated.
Plaintiff testified that, at the end of the stop, he and his passengers were lined up in front of about four officers. Plaintiff recalls Officer Estrada saying to him, “I wish you were drunk so I[had] a reason to take you in.” According to Plaintiff, Officer Estrada then told Martinez, “You know I can get you for drunk in public.” Martinez protested, saying, “How? You pulled me out of the back of the car.”
Finally, Officer Estrada advised them that, had they made a wrong move, he would have “busted a cap” in them right between the eyes, and that he and his partner liked to go to “night target practice.” After that, Plaintiff and his passengers were allowed to leave. Plaintiff was never told why Officer Estrada initially pulled him over, and no one was cited for any violation.
PROCEDURAL BACKGROUND
Plaintiff brought the present action, alleging claims under both federal and state law arising from the foregoing events. Defendants moved for summary judgment on the ground that they had immunity from suit on all claims. The district court granted their motion in part and denied it in part. The individual officers appeal the district court’s order to the extent that any officer was denied summary judgment on any claim.2 Plaintiff does not appeal.3
*1071The City does not appeal.4
A. Partial Denial of Summary Judgment for Federal Claims
The district court denied Officer Estrada qualified immunity for the traffic stop because, construing the facts in Plaintiffs favor, there was neither probable cause for the stop nor reasonable suspicion of illegal activity. The officer’s determination that Plaintiffs windows were rolled up and tinted did not qualify as a “reasonable mistake,” considering Plaintiffs testimony that the windows were rolled down and therefore not visible. The district court further denied qualified immunity to Officers Estrada and Keegan with regard to Plaintiffs claims that they used excessive force by handcuffing him in the absence of any information leading them to believe that he was potentially dangerous.
As to Plaintiffs claim that his detention was an unconstitutionally long seizure, the district court denied qualified immunity to all individual defendants. The court explained that it could not find as a matter of law that the individual defendants, as required by United States v. Sharpe, 470 U.S. 675, 686, 105 S.Ct. 1568, 84 L.Ed.2d 605 (1985), “diligently pursued a means of investigation that was likely to confirm or dispel their suspicions quickly, during which time it was necessary to detain the defendant.”
The district court then denied qualified immunity to various officers on Plaintiffs claims arising from the search of his car. Construing the facts in the light most favorable to Plaintiff, the district court concluded that the search of Plaintiffs car violated clearly established Fourth Amendment law because Plaintiffs consent to the search was not voluntary and because the traffic stop occurred without probable cause. Officers Estrada and Wheaton testified that they searched the car. After being asked whether Defendants Estrada, Tassio, or Prickett also searched the car, Officer Wheaton responded, “I think at one point everybody had their hands in something.” The district court therefore ruled that there was a triable issue of fact as to whether Defendants Estrada, Wheaton, Tassio, and Prickett violated Plaintiffs Fourth Amendment rights in searching his car. The court granted summary judg*1072ment to the other individual officers who were not implicated in the search.
The officer-defendants now appeal the denial of summary judgment, on qualified immunity grounds, as to all federal claims.
B. Partial Denial of Summary Judgment for State-Law Claims
Plaintiff also brought state-law claims against all individual officers and the City for false imprisonment, assault, battery, intentional infliction of emotional distress, negligence, negligent infliction of emotional distress, and a violation of California Civil Code section 52.1, which provides a private cause of action for interference with the exercise or enjoyment of one’s state or federal civil rights.5 The officers contended that they were immune from those state-law claims because they have discretionary immunity under California Government Code section 820.2, which states: “Except as otherwise provided by statute, a public employee is not liable for an injury resulting from his act or omission where the act or omission was the result of the exercise of the discretion vested in him, whether or not such discretion be abused.”6
Despite Defendants’ assertion of immunity, the district court partially denied summary judgment to various officers on *1073Plaintiffs state-law claims. With respect to the traffic stop itself, the district court denied summary judgment to Officer Estrada on Plaintiffs claims of false imprisonment, negligence, negligent and intentional infliction of emotional distress, and a violation of section 52.1. The court also denied summary judgment to Defendants Estrada, Wheaton, Tassio, and Prickett on Plaintiffs claims of negligence, negligent and intentional infliction of emotional distress, and a violation of section 52.1, predicated on the search of Plaintiffs car. The court denied summary judgment to all individual officers on Plaintiffs claims of false imprisonment, negligence, negligent infliction of emotional distress, and a violation of section 52.1, based on the length of the detention. Finally, the court denied summary judgment to Officers Estrada and Keegan on all of Plaintiffs state-law claims premised on the use of force. The district court granted summary judgment in favor of all other individual defendants on all other state-law claims.
In this appeal, the officer-defendants contend that Officers Estrada and Keegan are entitled to summary judgment as a matter of law on Plaintiffs assault and battery claims, because Plaintiff has not demonstrated that the officers used unreasonable force or that such force caused him injury, damages, loss, or harm. The officers further argue that all individual defendants are entitled to statutory immunity from the false imprisonment claim under California Government Code section 820.2.7 Finally, the officers assert that, if the individual defendants are entitled to qualified immunity under § 1983, then they bear no liability under California Civil Code section 52.1, because liability under the two statutes is coextensive.
STANDARD OF REVIEW
We review de novo the district court’s denial of summary judgment on the ground of qualified immunity. Act Up/Portland v. Bagley, 988 F.2d 868, 871 (9th Cir.1993). We must affirm a denial of summary judgment when, viewing the evidence in the light most favorable to the nonmoving party, there remain genuine issues of material fact or when the uncontroverted facts establish that the moving party is not entitled to prevail as a matter of law. Olsen v. Idaho State Bd. of Med., 363 F.3d 916, 922 (9th Cir.2004). “The determination of immunity is a question of law, which we review de novo.” Id.
JURISDICTION8
’ A court of appeals has jurisdiction over appeals from “final” orders. 28 U.S.C. § 1291. But as the Supreme Court explained in Mohawk Industries, Inc. v. Carpenter, -U.S.-, 130 S.Ct. 599, 605, 175 L.Ed.2d 458 (2009):
This Court ... has long given § 1291 a practical rather than a technical construction .... [T]he statute encompasses not only judgments that terminate an action, but also a small class of collateral rulings that, although they do not end the litigation, are appropriately deemed “final.”
(Internal quotation marks and citation omitted.) “Ordinarily a denial of a motion for summary judgment is not a final order *1074and thus [is] not appealable.” Abend v. MCA Inc., 863 F.2d 1465, 1482 n. 20 (9th Cir.1988). In Mitchell v. Forsyth, 472 U.S. 511, 530, 105 S.Ct. 2806, 86 L.Ed.2d 411 (1985), however, the Supreme Court held that “a district court’s denial of a claim of qualified immunity, to the extent that it turns on an issue of law, is an appealable ‘final decision’ within the meaning of ... § 1291 notwithstanding the absence of a final judgment.” In so holding, the Court reasoned that, because qualified immunity “is an immunity from suit rather than a mere defense to liability[,] ... it is effectively lost if a case is erroneously permitted to go to trial.” Id. at 526, 105 S.Ct. 2806. Thus, whether a denial of an immunity is immediately appealable turns on whether the immunity at issue is an immunity from suit or only a defense to liability.
We clearly have jurisdiction to review the district court’s order denying the officers qualified immunity with respect to Plaintiffs federal claims. Mitchell held that such jurisdiction lies under § 1291. Id. at 530, 105 S.Ct. 2806.
We cannot, however, exercise jurisdiction over the appeal from the denial of summary judgment to Officers Estrada and Keegan on Plaintiffs state-law claims for assault and battery. Essentially, the officers disagree with the district court’s interpretation of the facts. Because the officers appeal from an ordinary denial of summary judgment on those claims, as opposed to a denial of immunity, that section of the order is not an appealable final judgment under § 1291. We therefore dismiss the officers’ appeal with respect to the assault and battery claims.
We turn, then, to the officers’ appeal from the district court’s denial of immunity under California Government Code section 820.2 with respect to Plaintiffs false imprisonment claim. We agree with our sister circuits that the availability of an appeal depends on whether, under state law, the immunity functions as an immunity from suit or only as a defense to liability. See Ckesher v. Neyer, 477 F.3d 784, 793 (6th Cir.2007) (“An order denying statutory immunity is immediately appealable only if the state law provides immunity from suit, as opposed to immunity simply from liability.”); Aspen Orthopaedics & Sports Med., LLC v. Aspen Valley Hosp. Dist., 353 F.3d 832, 837-38 (10th Cir.2003) (same); Gray-Hopkins v. Prince George’s County, 309 F.3d 224, 231-32 (4th Cir. 2002) (same); Sheth v. Webster, 145 F.3d 1231, 1236-38 (11th Cir.1998) (per curiam) (same); Walton v. City of Southfield, 995 F.2d 1331, 1343 (6th Cir.1993) (same), superseded by statute as stated in Livermore ex rel. Rohm v. Lubelan, 476 F.3d at 397, 407-08 (6th Cir.2007); Griesel v. Hamlin, 963 F.2d 338, 339-41 (11th Cir.1992) (per curiam) (same); Napolitano v. Flynn, 949 F.2d 617, 621 (2d Cir.1991) (same); Brown v. Grabowski, 922 F.2d 1097, 1106-09 (3d Cir.1990) (same); Sorey v. Kellett, 849 F.2d 960, 962-63 (5th Cir.1988) (same); Marrical v. Detroit News, Inc., 805 F.2d 169, 172-74 (6th Cir.1986) (per curiam) (same).
The reasoning of our sister circuits on this point is straightforward. Under Erie Railroad Co. v. Tompkins, 304 U.S. 64, 58 S.Ct. 817, 82 L.Ed. 1188 (1938), federal procedure governs the appealability of an order. Marrical, 805 F.2d at 172; accord Budinich v. Becton Dickinson & Co., 486 U.S. 196, 198-99, 108 S.Ct. 1717, 100 L.Ed.2d 178 (1988). A denial of summary judgment is immediately appealable when the immunity is an immunity from suit, but not when it is a mere defense to liability. Mitchell, 472 U.S. at 526, 105 S.Ct. 2806. Accordingly, a denial is immediately appealable when “the state has extended an underlying substantive right to *1075the defendant official to be free from the burdens of litigation.” Marrical, 805 F.2d at 172.
Applying that standard, we hold that the district court’s denial of immunity under California Government Code section 820.2 is a final appealable decision within the meaning of § 1291. Although the question is not free from doubt, we conclude that, under California law, section 820.2 confers immunity from suit.
First, California case law suggests that section 820.2 provides immunity from suit, rather than mere immunity from liability. For example, the California Supreme Court has stated that the California Tort Claims Act (“Act”), which is codified in part at California Government Code section 820.2, “generally affords a public employee personal immunity from suit.” Caldwell v. Montoya, 10 Cal.4th 972, 42 Cal.Rptr.2d 842, 897 P.2d 1320, 1322 (1995) (emphasis added). The court also observed that “the ... Act expressly allows public employees to engage in certain acts and omissions free of suit.” Id., 42 Cal. Rptr.2d 842, 897 P.2d at 1331 (emphasis added).9
In another case, the California Supreme Court noted that, if the defendants’ “contention [of immunity under section 820.2] were sound, the individual defendants would be immune from suit.” Ramos v. County of Madera, 4 Cal.3d 685, 94 Cal.Rptr. 421, 484 P.2d 93, 98 (1971) (emphasis added). That court also has explained that section 820.2 protects officials’ decisions “which are sufficiently sensitive to justify a blanket rule that courts will not entertain a tort action alleging that careless conduct contributed to the governmental decision.” Johnson v. State, 69 Cal.2d 782, 73 Cal. Rptr. 240, 447 P.2d 352, 360-61 (1968) (emphasis added). Taken at face value, the California Supreme Court’s statements suggest that the statutory immunity is an immunity from suit.
Second, although California’s procedural rules concerning appealable orders do not allow interlocutory appeals from denials of immunity, Cal.Civ.Proc.Code § 904.1(a), California’s strict statutory classification of appealable orders has been relaxed by “the great expansion of the concept of excess of jurisdiction, allowing the prompt prevention of some unwarranted orders by writ of prohibition” and “[b]y permitting review of nonappealable orders by writ of mandamus.”10 9 B.E. Witkin, California Procedure, Appeal § 88(5th ed.2008). California courts sometimes have used these extraordinary writs to review otherwise nonappealable orders involving immunity claims under the Act. See, e.g., Jacqueline T. v. Alameda Cnty. Child Protective Servs., 155 Cal.App.4th 456, 66 Cal.Rptr.3d 157, 162-63 (2007) (discussing the reviewing court’s previous grant of a writ of mandate reversing the trial court’s denial of defendants’ statutory immunity claims at the summary judgment stage).
*1076Third, the policy underlying the Act suggests that section 820.2 confers immunity from suit. In Caldwell, 42 Cal.Rptr.2d 842, 897 P.2d at 1327, and in Johnson, 73 Cal.Rptr. 240, 447 P.2d at 360-61, the California Supreme Court cautioned that allowing suits against public employees might interfere with governmental decisionmaking. Moreover, in Barner v. Leeds, 24 Cal.4th 676, 102 Cal.Rptr.2d 97, 13 P.3d 704, 709 (2000), the court wrote:
Immunity is reserved for those basic policy decisions which have been expressly committed to coordinate branches of government, and as to which judicial interference would thus be unseemly. Such areas of quasi-legislative policy-making are sufficiently sensitive to call for judicial abstention from interference that might even in the first instance affect the coordinate body’s decision-making process.
(Internal quotation marks, citations, and alterations omitted.) The court thus articulated one of the “general costs of subjecting officials to the risks of trial — ... inhibition of discretionary action.” Mitchell, 472 U.S. at 526, 105 S.Ct. 2806 (internal quotation marks omitted).
Those considerations lead us to conclude that we have appellate jurisdiction to review the district court’s denial of statutory immunity under California Government Code section 820.2, because this section functions as an immunity from suit. But the question under California Civil Code section 52.1 is different. The officers’ only argument with respect to section 52.1 pertains to the extent of their liability — that is, whether it is coextensive with federal liability. This section does not create an entitlement to immunity from suit. Therefore, the district court’s rulings under section 52.1 are not presently appealable.
In summary, we have jurisdiction to review the denial of summary judgment, on grounds of qualified immunity, with respect to Plaintiffs federal claims. We also have jurisdiction to review the denial of summary judgment, on the ground of discretionary immunity under section 820.2, with respect to Plaintiffs state-law claim of false imprisonment. We turn now to a consideration of those issues on the merits.
DISCUSSION
A. The Traffic Stop
We affirm the district court’s denial of summary judgment on the ground of qualified immunity to Officer Estrada for the initial traffic stop. Qualified immunity shields government officers from the burdens of litigation “as long as their actions could reasonably have been thought consistent with the rights they are alleged to have violated.” Anderson v. Creighton, 483 U.S. 635, 638, 107 S.Ct. 3034, 97 L.Ed.2d 523 (1987). An officer is entitled to qualified immunity if, “[tjaken in the light most favorable to the party asserting the injury, ... the facts alleged [do not] show-the officer’s conduct violated a constitutional right” or if the right violated was not clearly established at the time of the violation. Saucier, 533 U.S. at 201, 121 S.Ct. 2151. We may “exercise [our] sound discretion in deciding which of the two prongs of the qualified immunity analysis should be addressed first in light of the circumstances in the particular case at hand.” Pearson, 129 S.Ct. at 818.
Viewing the facts in the light most favorable to Plaintiff, Officer Estrada violated Plaintiffs clearly established constitutional right to be free from unreasonable seizures by initiating a traffic stop without having a reasonable suspicion that Plaintiff was engaged in illegal activity. We must assume that Plaintiffs front windows were rolled down, and therefore not visible to Officer Estrada at the time he initiated the *1077traffic stop. In those circumstances, Officer Estrada’s determination that Plaintiffs windows were both rolled up and visibly tinted resulted from a mistake of fact. This mistake of fact, according to Officer Estrada, led him to conclude that the condition of Plaintiffs car violated California Vehicle Code sections 26708 and 26708.5(a).11 Officer Estrada therefore decided that he had reasonable suspicion to initiate a traffic stop.
“It has been settled law since the 1970’s that in order for a police officer to initiate an investigatory stop of a motorist, there must at least exist reasonable suspicion that the motorist is engaging in illegal activity.” Bingham v. City of Manhattan Beach, 341 F.3d 939, 948 (9th Cir.2003), abrogated on other grounds by Virginia v. Moore, 553 U.S. 164, 128 S.Ct. 1598, 170 L.Ed.2d 559 (2008), as recognized in Edgerly v. City of San Francisco, 599 F.3d 946, 956 n. 14 (9th Cir.2010). In order to form a reasonable suspicion, an officer must have “specific, articulable facts which, together with objective and reasonable inferences, form the basis for suspecting that the particular person detained is engaged in criminal activity.” United States v. Lopez-Soto, 205 F.3d 1101, 1105 (9th Cir.2000) (internal quotation marks omitted).
Even if an officer makes a mistake of fact, that mistake “will not render a stop illegal, if the objective facts known to the officer gave rise to a reasonable suspicion that criminal activity was afoot.” United States v. Mariscal, 285 F.3d 1127, 1131 (9th Cir.2002). As the Supreme Court has recognized:
[I]t is inevitable that law enforcement officials will in some cases reasonably but mistakenly conclude that probable cause is present. In such cases those officials should not be held personally liable. The qualified immunity standard gives ample room for mistaken judgments by protecting all but the plainly incompetent or those who knowingly violate the law.
Rodis v. City of San Francisco, 558 F.3d 964, 970-71 (9th Cir.2009) (internal quotation marks, citations, and alterations omitted), cert, denied, — U.S.-, 130 S.Ct. 1050, 175 L.Ed.2d 882 (2010). “Nevertheless, an officer’s belief in a mistaken fact must be held reasonably and in good faith.” United States v. Miguel, 368 F.3d 1150, 1154 (9th Cir.2004) (internal quotation marks omitted); see United States v. Dorais, 241 F.3d 1124, 1130-31 (9th Cir. 2001) (holding that it was a reasonable mistake of fact for an officer to pull over a *1078rental car for being stolen when the rental car company had reported it stolen, even though it was still actually a few hours short of being 48 hours overdue and therefore was not yet considered stolen under state law).
Because we hold that Officer Estrada’s mistake of fact was not reasonable, he is not entitled to qualified immunity. Officer Estrada asks us to conclude that it is a reasonable mistake to believe that windows that are rolled down and that cannot be viewed at all are in fact rolled up and tinted. This we cannot do. The qualified immunity standard is not so deferential to officers that it will allow a “chimera created by [an officer’s] imaginings [to] be used against the driver.” Mariscal, 285 F.3d at 1130; see Bingham, 341 F.3d at 946-48 (denying summary judgment on the basis of qualified immunity where the plaintiff testified that he had broken no traffic laws, but officer testified that he had seen the plaintiff drive across lane lines). Construing the facts in the light most favorable to Plaintiff, we must assume that Officer Estrada could not have seen Plaintiffs front car windows at all and that, indeed, the two made eye contact through the open windows. That being so, it would not be reasonable for Officer Estrada to believe that he had seen illegally tinted front windows.
The officer-defendants also argue that Officer Estrada had reasonable suspicion to stop and detain Plaintiff because the officer reasonably believed that Plaintiff was trying to avoid him by making several turns and then parking next to a dumpster in a darkened alley. In some circumstances, a suspect’s unprovoked, headlong flight can support an officer’s reasonable suspicion. Illinois v. Wardlow, 528 U.S. 119, 124, 120 S.Ct. 673, 145 L.Ed.2d 570 (2000). But avoidance of the police, standing alone, does not give rise to a particularized, reasonable suspicion that a person is committing a crime. Id. “[W]hen an officer, without reasonable suspicion or probable cause, approaches an individual, the individual has a right to ignore the police and go about his business.” Id. at 125, 120 S.Ct. 673 (citing Florida v. Royer, 460 U.S. 491, 498, 103 S.Ct. 1319, 75 L.Ed.2d 229 (1983)). As discussed above, Officer Estrada did not have reasonable suspicion to initiate the stop: Plaintiff had violated no traffic laws, and he did not engage in headlong flight upon seeing Officer Estrada. Thus, even if Officer Estrada reasonably suspected that Plaintiff was avoiding him, such noncooperation, without more, does not support a suspicion that Plaintiff was engaged in criminal activity. We therefore affirm the district court’s denial of qualified immunity to Officer Estrada for the initial traffic stop.
B. Excessive Force Claims
We affirm the district court’s denial of summary judgment on the ground of qualified immunity to Officers Estrada and Keegan for claims of excessive force. We agree with the district court’s observation that “some of the evidence supports defendants’ contention that they had legitimate safety and security concerns, [but] the facts construed in [Plaintiffs] favor[] fail to show any basis for the initial stop, the handcuffing, or Officer Estrada’s remarks directed to [Plaintiff].” The district court correctly noted that “there is no mistake of law which immunizes an officer for applying force to a suspect for ‘smarting off,’ nor to one detained without probable cause or reasonable suspicion.”
In the germinal case of Terry v. Ohio, the Supreme Court held that “an investigatory stop (temporary detention) and frisk (patdówn for weapons) may be conducted without violating the Fourth *1079Amendment’s ban on unreasonable searches and seizures” when two requirements are met. Arizona v. Johnson, — U.S.-, 129 S.Ct. 781, 784, 172 L.Ed.2d 694 (2009) (discussing Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968)). “First, the investigatory stop must be lawful.... Second, to proceed from a stop to a frisk, the police officer must reasonably suspect that the person stopped is armed and dangerous.” Id.
The first Terry condition was not met in this case; the traffic stop was unlawful because it did not rest on a reasonable suspicion that a violation of law had occurred. Therefore, it would not have been reasonable for Officers Estrada or Keegan to stop and frisk Plaintiff, let alone use physical force to extract him from his car, shove him against its door, and handcuff him for about half an hour.
The officers argue that the use of force was justified because Plaintiff turned a corner and then pulled over into a darkened alley near a dumpster. This maneuver led the officers to “believe[ ] that the Plaintiff had attempted to purposely evade Officer Estrada in an effort to cover up criminal activity and dispose of contraband.” But Plaintiffs avoidance of the police did not convert the initial stop into a legal seizure, nor did it render the level of force, used later, reasonable as a matter of law.
To determine whether the force used was objectively reasonable under the Fourth Amendment, we must “balanc[e] the ‘nature and quality of the intrusion’ on a person’s liberty with the ‘countervailing governmental interests at stake.’” Smith v. City of Hemet, 394 F.3d 689, 701 (9th Cir.2005) (en banc) (quoting Graham v. Connor, 490 U.S. 386, 396, 109 S.Ct. 1865, 104 L.Ed.2d 443 (1989)).
Thus, “[w]e first assess the quantum of force used to arrest [the plaintiff]” and then “measure the governmental interests at stake by evaluating a range of factors.” Factors we consider in assessing the government interests at stake include “[1] the severity of the crime at issue, [2] whether the suspect poses an immediate threat to the safety of the officers or others, and [3] whether he is actively resisting arrest or attempting to evade arrest by flight.” Courts may also consider “the availability of alternative methods of capturing or subduing a suspect.”
Davis v. City of Las Vegas, 478 F.3d 1048, 1054 (9th Cir.2007) (quoting Deorle v. Rutherford, 272 F.3d 1272, 1279-80 (9th Cir.2001); Graham, 490 U.S. at 396, 109 S.Ct. 1865; Smith, 394 F.3d at 701).
In this case, the use of force against Plaintiff occurred after he had complied with Officer Estrada’s requests for his driver’s license and registration. A check on his driver’s license and license plate numbers revealed nothing untoward. Plaintiff did not pose an immediate threat to anyone’s safety and was complying with the officer’s request to step out of his car. Although Officer Estrada may have thought that Plaintiffs choice of location in which to pull over was evasive, he was not “actively” attempting to evade arrest by flight. There was no evidence to suggest that Plaintiff was either armed or dangerous. Construing the facts in favor of Plaintiff, the use of force was not reasonable and violated clearly established constitutional law. Therefore, Officers Estrada and Keegan are not entitled to qualified immunity.
C. The Duration of the Detention
We affirm the district court’s denial of summary judgment to all individual defendants on the ground of qualified immunity for the length of Plaintiffs detention. At *1080the time of his detention, the law was clearly established that a prolonged seizure without a valid investigatory purpose was unreasonable in violation of the Fourth Amendment. See Royer, 460 U.S. at 500, 103 S.Ct. 1319 (“[A]n investigative detention must be temporary and last no longer than is necessary to effectuate the purpose of the stop.”). Although the Supreme Court has recognized that some investigatory stops made under Terry may be reasonable even if they are longer than the “momentary one[]” involved in that case, “the brevity of the invasion of the individual’s Fourth Amendment interests is an important factor in determining whether the seizure is so minimally intrusive as to be justifiable on reasonable suspicion.” United States v. Place, 462 U.S. 696, 709, 103 S.Ct. 2637, 77 L.Ed.2d 110 (1983).
We have held that “[t]he critical inquiry is whether the officers ‘diligently pursued a means of investigation that was likely to confirm or dispel their suspicions quickly, during which time it was necessary to detain the defendant.’ ” United States v. Torres-Sanchez, 83 F.3d 1123, 1129(9th Cir.1996) (quoting Sharpe, 470 U.S. at 686, 105 S.Ct. 1568). In this case, Plaintiff testified that he was detained for 45 minutes, during which he was in handcuffs for 25 to 30 minutes.12
The officers argue that there is no bright-line constitutional rule that investigatory stops of a certain duration are automatically unreasonable. They point out that, in Torres-Sanchez, 83 F.3d at 1128-29, we held a detention of 20 minutes to be reasonable under the circumstances presented in that case. The officers therefore contend that they are entitled to qualified immunity because, at the time Plaintiff was detained, the law was unclear as to how much longer than 20 minutes a suspect could be detained before the detention became unconstitutionally unreasonable.
The officers misconstrue our holding in Torres-Sanchez. We did not hold in that case that all detentions of 20 minutes are per se reasonable. Taken to its logical end, the officers’ argument would have us hold that, because the Supreme Court has declined to set a bright-line maximum time limit for investigatory stops, Sharpe, 470 U.S. at 685-86, 105 S.Ct. 1568, qualified immunity must be granted for all claims of excessively lengthy detention following an investigatory stop. Just because the required analysis in this case involves a fact-intensive determination of reasonableness, rather than application of a bright-line rule, does not mean that there are no situations in which clearly established constitutional violations can occur.
The legal test for deciding whether the length of a detention was unreasonable in violation of the Fourth Amendment was clearly established at the time that the officers detained Plaintiff, and we apply it here. In evaluating the reasonableness of the length of Plaintiffs detention, we “take care to consider whether the police [we]re acting in a swiftly developing situation” and emphasize that we “should not indulge in unrealistic second-guessing” of the officers’ actions. Id. at 686, 105 S.Ct. 1568. We also consider whether “a suspect’s actions contribute to the added delay about which he complains.” Id. at 688, 105 S.Ct. 1568. Finally, we determine whether “[i]n attempting to confirm or dispel his suspicions of illegal activity, [the officer] used ... threats of force, unnecessary delays, exaggerated displays of authority or other *1081coercive tactics.” Torres-Sanchez, 83 F.3d at 1129.
In this case, Officer Estrada had checked Plaintiffs license with dispatch 36 seconds after the stop. The officers argue, however, that they had reasonable suspicion to detain Plaintiff for a longer duration than would have been justified by a minor traffic stop for tinted windows alone. They contend that, “once Plaintiff failed to pull over on El Camino Real, but took evasive action to avoid Officer Estrada and parked in [a] darkened parking area adjacent to a darkened all[e]y, what started out as a minor traffic stop turned into something far different.” The officers contend that the prolonged detention was caused by Plaintiffs evasive action because it led them to believe that Plaintiff was disposing of drugs in a nearby dumpster and caused them to conduct a search in which they otherwise would not have engaged.
Plaintiffs behavior — pulling over into a darkened parking lot behind a building and turning off his car’s lights — certainly played a part in prolonging his detention. But even taking into account the inevitable investigatory delay caused by that behavior, the length of Plaintiffs detention was still unreasonable. Within five minutes of the traffic stop, a total of at least six additional officers had arrived at the scene to help search the area. Officers had removed Plaintiff and his passenger Martinez from the car, handcuffed them, and determined that they were not carrying any weapons. Most importantly, the partial audio recording of the stop reveals that Officer Estrada and his colleagues were not diligently pursuing a means of investigation that was likely to confirm or dispel their suspicions quickly. The recording establishes that the officers were not interrogating Plaintiff about his suspected possession or disposal of drugs. During the 15 minutes of the recording, they did not ask him about drugs even once. Nor did they inquire about the allegedly tinted windows that served as the pretext for the stop.
Plaintiff contends that he was detained not as part of an investigative stop, but for an “attitude adjustment.” The facts, seen in the light most favorable to him, support that conclusion. The prolonged detention was not for a valid investigatory purpose. The officers were not waiting for backup. They were not waiting for investigatory checks to be run or asking Plaintiff questions that would confirm or dispel their suspicions quickly (or at all). The officers knew everything that they needed to know within five to ten minutes of the stop’s initiation. Construing the facts in the light most favorable to Plaintiff, the delay occurred because, as Officer Estrada stated, he did not want to “let three little punks walk all over [him].” Officer Estrada told Plaintiff that he wanted to “let [Plaintiff] know that I’m the one in charge here, not you.” Prolonging a detention merely to engage in an “exaggerated displayf] of authority” is unreasonable and unconstitutional. Torres-Sanchez, 83 F.3d at 1129.
Reaching this conclusion does not require us to engage in “unrealistic second-guessing” of the officers at the scene. Sharpe, 470 U.S. at 686, 105 S.Ct. 1568. Officer Estrada himself evidenced an understanding that his behavior was unreasonable, when he said, “I don’t care about complaints.”
We therefore hold that an objectively reasonable officer responding to the scene of Plaintiffs detention would have known that its duration of 45 minutes without probable cause, during which the officers were not diligently pursuing their investigation was an unlawful detention of unreasonable duration in violation of clearly es*1082tablished Fourth Amendment law. We therefore affirm the district court’s denial of summary judgment on the ground of qualified immunity with respect to Plaintiffs length-of-detention claims against all of the individual officers who responded to the scene.
D. The Search of the Car
We affirm the district court’s denial of summary judgment on the ground of qualified immunity to the officers who participated in the search of Plaintiffs car. Construing the facts in the light most favorable to Plaintiff, his consent to the search was not voluntary and the search of his car was therefore unconstitutional. Plaintiffs Fourth Amendment right to be free of warrantless searches executed pursuant to nonvoluntary consent was clearly established at the time of the traffic stop. No reasonable officer would have believed the search to be lawful under that established law.
In the foundational case of Schneckloth v. Bustamonte, 412 U.S. 218, 228, 93 S.Ct. 2041, 36 L.Ed.2d 854 (1973), the Supreme Court held:
[T]he Fourth ... Amendment! ] require[s] that a consent not be coerced, by explicit or implicit means, by implied threat or covert force. For, no matter how subtly the coercion was applied, the resulting “consent” would be no more than a pretext for the unjustified police intrusion against which the Fourth Amendment is directed.
The factors to be considered in determining whether consent to a search was voluntary were also clearly established at the time of the traffic stop. Those factors include: “(1) whether defendant was in custody; (2) whether the arresting officers had their guns drawn; (3) whether Miranda warnings were given; (4) whether the defendant was notified that she had a right not to consent; and (5) whether the defendant had been told a search warrant could be obtained.” United States v. Patayan Soriano, 361 F.3d 494, 502 (9th Cir.2004) (internal quotation marks omitted). “No one factor is determinative in the equation ... but ‘many of this court’s decisions upholding consent as voluntary are supported by at least several of the factors.’ ” Id. (quoting United States v. Chan-Jimenez, 125 F.3d 1324, 1327 n. 3 (9th Cir.1997)). Because each factual situation surrounding consent to a search is unique, we may also take into account any other factors that we deem relevant. See, e.g., id. (weighing a threat from police to take away defendant’s children in determining whether her consent to search was coerced or voluntary).
The district court found that three of the five established factors weighed in favor of a finding that Plaintiffs consent to the search of his car was not voluntary. First, Plaintiff was in custody; second, only an incomplete Miranda warning was given; and third, Plaintiff was not notified that he could refuse the search. The court found that the other two factors weighed in favor of a voluntariness finding because the officers did not have their guns drawn and Plaintiff was not advised that a search warrant could be obtained.
Examining the totality of the circumstances surrounding Plaintiffs consent, the district court further held that a “reasonable jury could find that [Plaintiff] did not voluntarily consent to a search of his vehicle” because there were seven police officers present, it was approximately 2 a.m., and the “officers had control of [Plaintiffs] vehicle.” Having identified and applied the five factors used to determine voluntariness, the district court concluded that the alleged facts established that the officers violated Plaintiffs clearly established Fourth Amendment right against unrea*1083sonable searches. Construing the facts in Plaintiffs favor, the court further held that “ ‘it would be clear to a reasonable officer that his conduct was unlawful in the situation he confronted.’ ” (Quoting Saucier, 533 U.S. at 202, 121 S.Ct. 2151.)
The officers analogize this case to Torres-Sanchez, 83 F.3d at 1129-30, in which we held that consent given to a police search of the defendant’s car during a traffic stop was voluntary. This case, however, is distinguishable. In Torres-Sanchez, the suspect was asked three times to confirm his consent to search the car that he was driving. See id. at 1126. Moreover, he was not subjected to any “threats of force, unnecessary delays, exaggerated displays of authority or other coercive tactics” by the sole officer who pulled him over. Id. at 1129.
This case is more like Chan-Jimenez, 125 F.3d at 1326, in which we held that the motorist had been seized because the police officer had retained possession of his driver’s license and vehicle’s registration. Like Plaintiff, the motorist in Chan-Jimenez was not handcuffed at the moment that he gave his oral consent. See id. at 1325. Looking at the totality of the circumstances, however, we held that the officer had “manifested an intent to restrain [the plaintiffs] freedom.” Id. at 1326. We further held that the officer’s action of putting his hand on his gun, without drawing it, “let [the plaintiff] know that there could be adverse consequences for any failure to submit to authority. A reasonable person in [the plaintiffs] position would not have felt free to leave or to ignore the officer’s presence and go about his business.” Id. Those factors led us to hold that Chan-Jimenez had been seized at the time that he gave his consent. Id. at 1327. His seizure, together “with the fact that the incident took place on a desert highway, with nobody else in sight,” led us to conclude that the officer’s request “would have been viewed by a reasonable person essentially as a command to allow a search” of his vehicle. Id.
In this ease, the officers’ handcuffing Plaintiff “manifested an intent to restrain [his] freedom.” Id. at 1326. Officer Estrada also led Plaintiff by the arm to his car before requesting his consent, thereby conveying his continued physical authority. Having already been handcuffed and verbally berated by Officer Estrada, Plaintiff “kn[e]w that there could be adverse consequences for any failure to submit to authority. A reasonable person in [Plaintiffs] position would not have felt free to leave or to ignore the officer’s presence and go about his business.” Id. Therefore, we conclude that Plaintiff was seized at the time that he gave his consent.
Furthermore, it was late at night, Plaintiff still had not been told why he was pulled over, and he was surrounded by seven police officers, some of whom were actively searching the area around his vehicle. Those facts make it clear that Officer Estrada’s request that Plaintiff identify the vehicle and that he provide consent to the search “would have been viewed by a reasonable person essentially as a command to allow a search.” Id. at 1327. Our conclusion is bolstered by the fact that the officers maintained physical control of Plaintiff for a significant period of time after he gave consent. After obtaining consent, Officer Estrada immediately walked Plaintiff by the arm back to his patrol car, and another officer placed Plaintiff in its backseat.
The officers’ argument that they could legally conduct a protective nonconsensual search of Plaintiffs car also fails. In Michigan v. Long, 463 U.S. 1032, 1049, 103 S.Ct. 3469, 77 L.Ed.2d 1201 (1983), the Supreme Court held that
the search of the passenger compartment of an automobile, limited to those *1084areas in which a weapon may be placed or hidden, is permissible if the police officer possesses a reasonable belief based on “specific and articulable facts which, taken together with the rational inferences from those facts, reasonably warrant” the officer in believing that the suspect is dangerous and the suspect may gain immediate control of weapons,
(quoting Terry, 392 U.S. at 21, 88 S.Ct. 1868).13 In that case, the suspect was intoxicated, had been driving dangerously, and there was a large knife in plain view inside his car, which the suspect was about to reenter. Id. at 1050, 103 S.Ct. 3469. The present case is not analogous because there existed no specific and articulable facts that would reasonably warrant a belief that Plaintiff was dangerous or that he might gain immediate control of a weapon.
For those reasons, we hold that Plaintiffs consent to the search of his car was not voluntary. Accordingly, the search was unconstitutional under law that was clearly established at the time. We therefore affirm the district court’s denial of summary judgment to Defendants Estrada, Wheaton, Tassio, and Prickett on the ground of qualified immunity for the search of Plaintiffs car, because there is evidence in the record to permit a finding that each of those officers was involved in the unconstitutional search.
E. False Imprisonment and Discretionary Immunity
As to Plaintiffs false imprisonment claim, the officers argue that they are entitled to discretionary immunity under California Government Code section 820.2, which states:
Except as otherwise provided by statute, a public employee is not liable for an injury resulting from his act or omission where the act or omission was the result of the exercise of the discretion vested in him, whether or not such discretion be abused.
The officers contend that the decision to stop and detain Plaintiff was within their discretion. We disagree and affirm the district court’s denial of summary judgment on Plaintiffs false imprisonment claim.
As a matter of law, section 820.2 immunity does not apply to an officer’s decision to detain or arrest a suspect. Gillan, v. City of San Marino, 147 Cal.App.4th 1033, 55 Cal.Rptr.3d 158, 174 (2007). “A ‘workable definition’ of immune discretionary acts draws the line between ‘planning’ and ‘operational’ functions of government.” Caldwell, 42 Cal.Rptr.2d 842, 897 P.2d at 1325-26 (quoting Johnson, 73 Cal.Rptr. 240, 447 P.2d at 360.) “Immunity is reserved for those ‘basic policy decisions [which have] ... been [expressly] committed to coordinate branches of government,’ and as to which judicial interference would thus be ‘unseemly.’ ” Gillan, 55 Cal.Rptr.3d at 174 (alterations in original) (quoting Johnson, 73 Cal.Rptr. 240, 447 P.2d at 360). A police officer’s deci*1085sion to detain or arrest a suspect is “not a basic policy decision, but only an operational decision by the police purporting to apply the law.” Id. Thus, the immunity provided by California Government Code § 820.2 does not apply to claims of false imprisonment or false arrest predicated on an officer’s detaining a suspect without reasonable suspicion or probable cause. See Gillan, 55 Cal.Rptr.3d at 174 (holding that police officers were not immune to suit under section 820.2 for a false arrest claim). We therefore affirm the district court’s denial of summary judgment on the officers’ claims of discretionary immunity with regard to Plaintiffs false imprisonment claim.
CONCLUSION
We affirm the district court’s order denying the officers’ motion for summary judgment on the ground of qualified immunity with respect to Plaintiffs § 1983 claims. We also affirm the district court’s order denying the officers’ motion for summary judgment on the ground of discretionary immunity under California Government Code section 820.2 with respect to Plaintiffs false imprisonment claims. The remaining portions of the officers’ appeal are dismissed. The case is remanded to the district court for further proceedings.
AFFIRMED in part, DISMISSED in part, and REMANDED. Costs on appeal awarded to Plaintiff-Appellee.

. Officer Estrada maintains that Plaintiff’s front driver-side window was rolled up and illegally tinted. Therefore, he contends, he had probable cause to stop Plaintiff’s car. Officer Estrada further maintains that, because the windows were tinted, he could not determine the races of the car’s occupants before pulling it over. For purposes of qualified immunity and summary judgment determinations, however, we view all facts in the light most favorable to Plaintiff, as the non-moving party. See Saucier v. Katz, 533 U.S. 194, 201, 121 S.Ct. 2151, 150 L.Ed.2d 272 (2001), ovetruled in other part by Pearson v. Callahan, 555 U.S. 223, 129 S.Ct. 808, 172 L.Ed.2d 565 (2009); Olsen v. Idaho State Bd. of Med., 363 F.3d 916, 922 (9th Cir.2004). We recount the facts accordingly.

. In their opening brief, the individual officer-defendants presented no argument on their *1071own behalf concerning the claims for intentional infliction of emotional distress, negligence, and negligent infliction of emotional distress. Accordingly, those issues are waived, see Eberle v. City of Anaheim, 901 F.2d 814, 818 (9th Cir.1990), and we do not consider them. Only the issue of state statutory immunity with regard to the false imprisonment claim remains.

. The district court granted summary judgment to all individual defendants except Officer Estrada with regard to the traffic stop, and to all individual defendants except Officers Estrada and Keegan for handcuffing Plaintiff. The court also granted summary judgment to Officers Keegan, Romero, and Ayres for the search of Plaintiff's car. It further granted summary judgment to all individual defendants with regard to Plaintiff's claims for race discrimination under the Equal Protection Clause of the Fourteenth Amendment and for excessive force under the Fifth Amendment's Due Process Clause. Moreover, the court granted summary judgment to the City on Plaintiff's § 1983 claims under Monell v. Department of Social Services, 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978). Those rulings are not before us.

. The City argued before the district court that it was entitled to immunity to the same extent that its individual officers were immune. In support, the City pointed to California Government Code section 815.2(b), which provides: “Except as otherwise provided by statute, a public entity is not liable for an injury resulting from an act or omission of an employee of the public entity where the employee is immune from liability.” Accepting the City's argument, the district court granted summary judgment to the City to the same extent that it granted the individual officers’ motions for summary judgment.

. California Civil Code section 52.1 provides, in relevant part:
(a) If a person or persons, whether or not acting under color of law, interferes by threats, intimidation, or coercion, or attempts to interfere by threats, intimidation, or coercion, with the exercise or enjoyment by any individual or individuals of rights secured by the Constitution or laws of the United States, or of the rights secured by the Constitution or laws of this state, the Attorney General, or any district attorney or city attorney may bring a civil action for injunctive and other appropriate equitable relief in the name of the people of the State of California, in order to protect the peaceable exercise or enjoyment of the right or rights secured. An action brought by the Attorney General, any district attorney, or any city attorney may also seek a civil penalty of twenty-five thousand dollars ($25,-000). If this civil penalty is requested, it shall be assessed individually against each person who is determined to have violated this section and the penalty shall be awarded to each individual whose rights under this section are determined to have been violated.
(b) Any individual whose exercise or enjoyment of rights secured by the Constitution or laws of the United States, or of rights secured by the Constitution or laws of this state, has been interfered with, or attempted to be interfered with, as described in subdivision (a), may institute and prosecute in his or her own name and on his or her own behalf a civil action for damages, including, but not limited to, damages under Section 52, injunctive relief, and other appropriate equitable relief to protect the peaceable exercise or enjoyment of the right or rights secured.

. The officers also asserted "due care" immunity under California Government Code section 820.4, immunity for peace officers making an arrest based on probable cause under California Penal Code sections 847(b) and 836.5, lawful privilege to detain under Asgari v. City of Los Angeles, 15 Cal.4th 744, 63 Cal.Rptr.2d 842, 937 P.2d 273, 281 (1997) (clarifying that, in order to establish the tort of false imprisonment under California law, a confinement must be without lawful privilege), and privilege to use force under California Penal Code section 835a. The district court rejected the officers’ assertion of those immunities with respect to various claims. On appeal, the officers argued for the first time in their reply brief that the district court erred in denying the individual officers immunity under California Penal Code sections 836.5 and 847 and California Government Code section 820.4. Because those issues were not raised in the officers' opening brief, they have been waived. See Eberle, 901 F.2d at 818. The officers at no time challenged the district court’s partial denial of summary judgment on the basis of lawful privilege to detain under Asgan, or privilege to use force under Penal Code section 835a. Therefore, we decline to address those issues.

. The officers also assert immunity for the City under California Government Code section 815 with respect to Plaintiff's claims of negligence, negligent infliction of emotional distress, and intentional infliction of emotional distress. We do not reach that argument because only the individual defendants have appealed; they cannot claim an immunity that protects only the City.

. The district court had jurisdiction pursuant to 28 U.S.C. §§ 1331, 1343(a)(3), and 1367(a).

. Additionally, the California Supreme Court wrote:
We do not mean to suggest that a high official’s public explanation of the reasons for his basic policy decision should be immune from suit if his comments are themselves actionable unless privileged. We merely express concern that public commentary might be discouraged by allowing suits in which such commentary would provide evidence of the allegedly impermissible motives behind the basic policy decision.
Caldwell, 42 Cal.Rptr.2d 842, 897 P.2d at 1327 n. 4 (emphases added) (citations and original emphases omitted).

. California's procedural treatment of interlocutory orders involving section 820.2 is instructive as to the nature and scope of the immunity under state law, even though federal procedure governs here.

. California Vehicle Code section 26708 provided, at the time of the traffic stop, in relevant part:
(a) (1) A person shall not drive any motor vehicle with any object or material placed, displayed, installed, affixed, or applied upon the windshield or side or rear windows.
(b) This section does not apply to any of the following:
(4) Side windows that are to the rear of the driver.
(8) The rear window or windows, if the motor vehicle is equipped with outside mirrors on both the left- and right-hand sides of the vehicle that are so located as to reflect to the driver a view of the highway through each mirror for a distance of at least 200 feet to the rear of the vehicle.
California Vehicle Code section 26708.5(a) provides:
No person shall place, install, affix, or apply any transparent material upon the windshield, or side or rear windows, of any motor vehicle if the material alters the color or reduces the light transmittance of the windshield or side or rear windows, except as provided in subdivision (b), (c), or (d) of Section 26708.

. Although the officers assert that the detention lasted only 28 minutes, we again must construe the facts in the light most favorable to Plaintiff.

. We note, for good measure, that the Supreme Court's recent decisions in Arizona v. Johnson, 555 U.S. 323, 129 S.Ct. 781, 172 L.Ed.2d 694 (2009), and Arizona v. Gant, U.S. -, 129 S.Ct. 1710, 173 L.Ed.2d 485(2009), do not affect the analysis in this case. Johnson addressed an issue not presented by this case, that is, whether an officer's authority to conduct a pat down ends after the officer inquires into matters unrelated to the justification for the initial traffic stop. 129 S.Ct. at 788. Gant dealt with a search incident to arrest conducted after the suspect had been handcuffed and locked in the back of a patrol car. 129 S.Ct. at 1714. Here, Defendants do not argue the search-incident-to-arrest exception to the Fourth Amendment's prohibition against warrantless searches.
