Mr. Grissom, appearing pro se, appeals. Exercising jurisdicti on under 28 U.S.C. § 1291, we affirm. 1
I. BACKGROUND

A. Factual History The following summarizes the facts presen ted to the district court on summary judgment. We review the re cord in the light most favo rable to the nonmovant, Mr. Grissom. Emmett v. Armstrong , 973 F.3d 1127, 1130 (10th Cir. 2020). The evidence included a declaration from Corrections Superv isor Andrew Palm and an affidavit from Mr. Grissom setting forth their accounts of the altercation between them. ROA, Vol. I at 818-22, 852-64. It also incl uded a video of the incident taken from a prison surveillance

camera. See ROA, Vol. III. 2 On November 25, 2017, M r. Grissom was imprisoned at the Kansas Department of Corrections (“KDOC”) El Dorado facility . Officer Palm walked by Mr. Grissom’s

1 We construe Mr. Grissom’s pro se fili ngs liberally, but we do not act as his advocate. See Garrett v. Selby Con nor Maddux & Janer , 425 F.3d 836, 840 (10th Cir. 2005).

2 The video was sealed in district court. Appellees argue it should continue to be sealed to protect prison security. In their publicly filed brie f, they nonetheless describe in detail the altercation between Officer Palm and Mr. Grissom based upon, and with citations to, the video. So did the district court in its summary judgment order. The video will remain sealed, but Appellees have waived any interest in sealing written descriptions of the altercation based on the video in their brief or in this Order and Judgment. Based on the parties’ filings in this court on the seal ing issue, we remanded to the district court for factual findings rega rding Mr. Grissom’s ac cess to the video. On remand, the district court found he “h ad the opportunity to view the video upon Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 23 second-floor cell and saw him holding a bag containing a “green leafy substance.” Id. at 818. He asked the control booth to open Mr. Grissom’s door so he could determine whether the substance was contraband. When the door opened, Officer Palm asked to see the bag. Mr. Grissom told him the bag contai ned sage and to verify with the Captain’s Office that he could have it for religious purposes. Mr. Grissom gave the bag to Officer Pa lm but became upset at the way Officer Palm was handling it, telling him to stop trying to open the bag “because he was unclean and going to contaminate [it].” Id. at 853. When Officer Palm asked to see a box Mr. Grissom was holding, Mr. Grissom “reached for the sage” and said, “then give me that back.” Id. (quotations omitted). Officer Palm believed Mr. Grissom was “aggressively attempt[ing] to snatch th e bag from [his] hands.” Id. at 819. Mr. Grissom countered that Officer Palm “overreacted,” complaining that he was “simply going to trade the . . . box . . . for the [sage that] [Officer] Palm was holding.” Id. at 850. Mr. Grissom asked to see the Captain to resolve the matter. Officer Palm ordered Mr. Grissom to turn around to be hand cuffed for transit to the Captain’s Office. When Officer Palm or dered him to turn his wrist, Mr. Grissom

request.” Mem. & Order at 6, Grissom v. Palm , No. 19-3178-EFM (D. Kan. Aug. 9, 2022), ECF # 81. Further, on remand, the dist rict court, in its July 15, 2022 order, invited Mr. Grissom to submit any additional evidence to that court, but he did not do so. In a filing to this court on August 17, 2022, Mr. Grissom continues to contest this matter, but he has not shown that the di strict court’s finding in its August 9, 2022 order was clearly erroneous. See Ramos v. Banner Health , 1 F.4th 769, 777 (10th Cir. 2021) (“We review the district court’s fi ndings of fact for clear error.”). Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 34 replied that he had “shoulder inflexib ility” and the handcuffs did not “allow for
movement.” Id. at 851. Officer Palm had previo usly handcuffed Mr. Grissom and was aware that he preferred “two sets of cuffs,” but he was unable to do so here because Mr. Grissom was “moving his arm in a back and forth motion and refusing to turn his wrist to allow the first handcuff to be secured on his wrist.” Id. at 820. Mr. Grissom turned back toward O fficer Palm, who “issued an ‘office r needs assistance’ call” as he tried to handcuff Mr. Grissom. Id. The situation quickly deteriorated. Officer Palm claimed that Mr. Grissom abruptly turned, knocking the handcuffs “across the cel l” and prompt ing him to “assume[] a defensive fighting stance and bl ock[] several strikes from [Mr.] Grissom.” Id. at 821. Mr. Grissom argued that Offi cer “Palm was the culprit who was throwing punches while [he] deflected them.” Id. at 854. Mr. Grissom denied knocking the handcuffs across the cell and claimed that O fficer Palm instead “used them like brass knuckles in his attempts to strike [him].” Id. at 853-54. Mr. Grissom said he pushed Officer Pa lm back toward th e cell’s opening but Officer Palm grabbed his arm and tried to pull him forward. Officer Palm said he retreated out of the cell and “deployed OC.” Id. at 821. 3 He claimed that Mr. Grissom also exited the cell, striking him and trying to throw him over the second-floor railing.

3 “OC” refers to oleoresin capsicum , a chemical agent commonly known “as pepper spray or mace.” Id. at 771. Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 45 To defend himself, Officer Palm said that he repeatedly st ruck Mr. Grisso m in the head with the metal OC canister. Mr. Grissom said he struck Officer Palm only once, and only in the stomach while Officer Palm had placed him in a painful headlock. Mr. Gr issom denied tr ying to throw Officer Palm over the railing, stating that in stead “he was going to body slam [him] onto the . . . floor they were standing on.” Id. at 854. Mr. Grissom said that he grabbed Officer Palm’s legs, “picked him up,” but then “simply laid him ‘gently’ onto the tier” and complied with responding officers’ request to cuff up. Id. at 861. The video of the incident came from a camera on the other side of the tier. 4 The camera did not record sound, but the video mos tly confirmed Officer Palm’s version. It showed the following. After Mr. Grissom’s cell door opened, O fficer Palm and Mr. Grissom spoke for about two minutes. Mr. Gri ssom pointed and moved his arms while speaking. Officer Palm began one of three attempts to ha ndcuff him. After the second attempt, Correctional Officer Abraham Loew en arrived and stood to the side of the cell. On the third attempt, Mr. Grissom jerked his ar m away from Officer Pa lm, who pushed Mr. Grissom against the inside cell wall. Offi cer Palm quickly backed off and assumed a fighting stance. He and Mr. Grissom punc hed and blocked punches for five to ten seconds. Mr. Grissom advanced toward th e cell door. Officer Palm backed up and

4 Mr. Grissom’s cell was located amon g a second-tier row of cells. The walkway outside the cells ha d a railing to prevent a fall to the ground level. Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 56 grabbed an OC cannister from his utility belt. Two more officers arrived. One stood several feet away from Mr. Grissom’s cell and th e other stood near the top of the stairs as other inmates approached. Mr. Grissom came through the cell door to ward Officer Palm, prompting him to discharge a burst of OC spray into Mr. Gr issom’s face. As Mr. Grissom emerged from his cell, he swung his fist at Officer Palm ’s head, making contact. Mr. Grissom then wrapped his arm around Officer Palm’s waist. Attempting to free himself, Officer Palm repeatedly struck Mr. Grissom in the head w ith his OC cannister. Another inmate then attacked two of the responding officers. As Officer Palm and Mr. Grissom strugg led, Mr. Grissom grabbed Officer Palm’s right leg and began to pick him up next to the second-floor guard rail. Both men fell on the floor outside the cell. O fficer Loewen pushed Mr. Gri ssom back into his cell while Officer Palm discharged his OC cannister again toward Mr. Grissom. Responding officers secured the scene, ha ndcuffed Mr. Grissom, and esco rted him out of the cell. The attending nurse at the prison infirmary examined Mr . Grissom. She reported that he had an abrasion to his right shin; se veral marble-sized knots on his scalp; a red, swollen left ear; an abrasion w ith bruising to his upper back ; a scratch on his neck and under his lower lip; and burning sensations in his eyes and on his skin from the OC. Mr. Grissom complained of a headache, dizziness, and blurred vision. A KDOC internal investigation found that Officer Palm’s poor judgment, lack of communication, and unnecessary force escalate d the situation. He received a three-day Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 67 suspension. KDOC penalized Mr. Grissom with segregation time for battery and disobeying orders. In January 2018, KDOC transferred him to its Hutchinson facility.
B. Procedural History Mr. Grissom sued Officer Palm, Officer Loewen, an d other KDOC personnel under 42 U.S.C. § 1983. He claimed Eighth Amendment violations because Officer Palm used excessive force, Officer Loewen failed to intervene to protect him, and others approved of Officer Palm’s actions and retaliated against him. In response to the Defendants’ summa ry judgment motion, Mr. Grissom argued only his excessive force claims against Office rs Palm and Loewen. The district court thus dismissed the claims against the other Defe ndants. It then determined that Officers Palm and Loewen were entitled to qualified im munity and granted su mmary judgment to them because (1) “the video confirm[ed] . . . [Mr. Grissom’s] aggression and violent assault on [Officer] Palm”; and (2) Mr. Grissom identified “no case finding a constitutional violation under similar circum stances.” ROA, Vol. I at 917, 918. Mr. Grissom appeals the summary judgment based on qualified immunity granted to Officers Palm and Loewen.
II. DISCUSSION
A. Standard of Review and Qualified Immunity “We review de novo the district court’ s order granting summary judgment . . . on qualified-immunity grounds.” Gutteridge v. Oklahoma , 878 F.3d 1233, 1238 (10th Cir. 2018). “When a defendant asserts qualified im munity at summary ju dgment, the burden shifts to the plaintiff, who must clear two hurdles in order to defeat the defendant’s Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 78 motion.” Id. (quotations omitted). The plaintiff mu st “show (1) a reasonable jury could find facts supporting a violation of a c onstitutional right, which (2) was clearly established at the time of the defendant’s conduct.” Gutierrez v. Cobos , 841 F.3d 895, 900-01 (10th Cir. 2016) (quota tions omitted). “We have discretion to address the two qualified-immunity prongs in whatever orde r is appropriate under the circumstances.” Toevs v. Reid , 685 F.3d 903, 910 (10th Cir. 2012). In conducting our analysis, we “view the evidence, and all inferences arising from that evidence, in the light mo st favorable to the nonmoving party[;] . . . this usually means adopting the plaintiff’s version of the facts.” Emmett v. Armstrong , 973 F.3d 1127, 1130 (10th Cir. 2020) (ellip sis and quotations omitted). But “[w]hen the record on appeal contains video evidence of the incident in question, . . . we will accept the version of the facts portrayed in the video . . . to the extent that it blatantly contradicts the plaintiff’s version of events.” Id. at 1131 (brackets and quotations omitted).
B. Excessive Force “[C]laims of excessive force involving convicted prisoners arise under the Eighth Amendment.” Estate of Booker v. Gomez , 745 F.3d 405, 419 (1 0th Cir. 2014). The plaintiff must establish objec tive and subjective elements. Redmond v. Crowther , 882 F.3d 927, 936 (10th Cir. 2018). The objectiv e element “asks if the alleged wrongdoing was objectively harmful enough to esta blish a constitutional violation.” Id. (quotations omitted). The subjective element concerns whether “the official[ ] acted with a sufficiently culpable state of mind,” such that he “use[d] force maliciously and Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 89 sadistically for the very purpose of causing harm, rather than in a good faith effort to maintain or restore discipline.” Redmond , 882 F.3d at 936 (quotations omitted). On appeal, Mr. Grissom pursues three ex cessive-force theories: (1) “assault and battery,” Aplt. Br. at 6; (2) use of regular-si zed handcuffs; and (3) fa ilure to intervene. But even if we assume that Officer Palm used excessive force, we affirm because Mr. Grissom has failed to show a constitutio nal violation based on clearly established law.
C. Clearly Established Law “A clearly established right is one that is sufficiently clear that every reasonable official would have understo od that what he is doing violates that right.” Mullenix v.
Luna , 577 U.S. 7, 11 (2015) (per curiam) (quotations omitted ). The Supreme Court has “repeatedly told courts not to define clea rly established law at too high a level of generality.” City of Tahlequah v. Bond , 142 S. Ct. 9, 11-12 (2021) (per curiam). “The dispositive question is whethe r the violative nature of particular conduct is clearly established.” Mullenix , 577 U.S. at 12. Accordingly, our “inquiry must be undertaken in light of the specific context of the case, not as a broad general proposition.” Id. (quotations omitted). “A Government official’s conduct violat es clearly established law when, at the time of the challenged conduct,” “existing prec edent . . . [has] placed the statutory or constitutional question beyond debate.” Ashcroft v. al-Kidd , 563 U.S. 731, 741 (2011). “[T]he ‘clearly established’ analysis” requi res “identify[ing] a case where an officer act[ed] under similar circumstances.” White v. Pauly , 137 S. Ct. 548, 552 (2017) (per Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 910 curiam). In other words, “officers are entitled to qualified immunity unless existing precedent squarely gov erns the specific fact s at issue.” Kisela v. Hughes , 138 S. Ct. 1148, 1153 (2018) (per curiam) (quotations omitted). “A Supreme Court or Tenth Circuit decision on point or the weight of authority from other c ourts can clearly establish a right.” Ashaheed v. Currington , 7 F.4th 1236, 1246 (10t h Cir. 2021) (quotations omitted). Although “general stat ements of the law are not inh erently incapable of giving fair and clear warning to officers,” the unlawfulness of their condu ct “must be apparent” “in the light of pre-existing law.” White , 137 S. Ct. at 552 (quotations omitted). Assault & Battery The surveillance video shows that (1 ) Officer Palm attempted to handcuff Mr. Grissom, (2) Mr. Grissom jerked his hand away on the third attempt, and (3) the situation deteriorated into a violent struggl e as Officer Palm tried to gain control of Mr. Grissom and defend agai nst his aggression. Offi cer Palm repeatedly struck Mr. Grissom on the head with the metal OC canister and trie d to hit him in the face with the handcuffs. 5 Mr. Grissom fails to identify a single Su preme Court or Tenth Circuit case to show clearly established law. Instead, he identif ies two Eleventh Circu it cases, but because

5 Mr. Grissom does not challenge Officer Palm’s application of OC spray as excessive. “Issues not raised in the opening brief are deemed aba ndoned or waived.” Tran v. Trs. of State Colls. in Colo. , 355 F.3d 1263, 1266 (10th Cir. 2004) (quotations omitted). Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 1011 they concerned distinguishable circumstance s, neither would have put a reasonable officer in Officer Palm’s position on no tice of a constitutional violation. First, he mentions Johnson v. Breeden , 280 F.3d 1308 (11th Cir. 2002), abrogated on other grounds as recognized in Patel v. Lanier Cnty. , 969 F.3d 1173, 1185-86 (11th Cir. 2020). It affirmed a jury’s award of damages against correcti ons officers who had taken the prisoner into his cell, choked and p unched him, and then threw him to the floor, where they kicked him and beat him “with batons until he lost consciousness.” Id. at 1312. But Johnson , unlike here, did not involve an in mate initiating a struggle during an officer’s handcuffing attempts that escal ated into a fight w ith that officer. Second, Mr. Grissom also cites, Fennell v. Gilstrap , 559 F.3d 1212, 1220 (11th Cir. 2009), abrogated on other grounds as recogn ized in Patel v. Lanier Cnty. , 969 F.3d 1173, 1185-86 (11th Cir. 2020). There, six o fficers struggled to handcuff a combative pretrial detainee. Another officer entered the room and tried to kick the detainee’s arm so he would release his grip on an officer, but he inadvertently kicked the detainee in the face and seriously injured him. Id. at 1214, 1219. The Eleven th Circuit determined that the officer who kicked the detainee did not us e excessive force because the detainee was resisting the handcuffing attempts and “did no t let go of [the other officer’s] arm despite being punched.” Id. at 1218-19. This factual scenario differs from Officer Palm’s efforts to defend himself, even if he did so aggre ssively, against Mr. Grissom’s attacks. The cases Mr. Grissom cites therefore did not clearly establish the law. 6

6 Although Mr. Grissom bears the burden of showing clearly established law, see Gutierrez , 841 F.3d at 900-01, we also have not found a case that would have put Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 1112 We have recognized that “when prison offi cials must act to preserve internal order and discipline,” they enjoy “wide-ranging deference.” Redmond , 882 F.3d at 938 (quotations omitted). “[A] prison guard, to ma intain control of inmates, must often make instantaneous, on-the-spot deci sions concerning the need to apply force without having to second-guess himself.” Sampley v. Ruettgers , 704 F.2d 491, 496 ( 10th Cir. 1983). This explains the lack of case law that would make it “sufficiently clear that every reasonable official [in Officer Palm’s position],” Mullenix , 136 S. Ct. at 308, would have understood that the force he employed against Mr. Grissom—in both defending against his aggression and restori ng order—violated the Eighth Amendment. See Ashaheed , 7 F.4th at 1247 n.6 (noting that factual specificity between prior precedent and the instant case is “especially important” in th e excessive-force context becaus e “officers are forced to make split-second judgments about the amount of force that is necessary” (alterations and quotations omitted)). Decisions in this circuit and elsewhere have rejected excessive-force claims where one or more corrections officers used force to gain control of a combative or resistant

a reasonable officer in Officer Palm’s posit ion on notice that his actions violated the Eighth Amendment. Mr. Grissom used for ce and grappled violently with Officer Palm. This differs, for instan ce, from the prisoner’s claim in Wilkins v. Gaddy , 559 U.S. 34 (2010), where a corrections officer allegedly slammed the prisoner onto the concrete floor and then punched, kicked, kneed, and choked him simply for requesting a grievance form. Id. at 38 (holding that “[a]n in mate who is gratuitously beaten by guards does not lose his ability to pursue an ex cessive force claim merely because he has the good fortune to escape without serious injury”). Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 1213 prisoner. 7 Particularly instructive is Miller v. Glanz , 948 F.2d 1562 (10th Cir. 1991), in which this court addressed tw o separate incidents and reac hed different outcomes under the Eighth Amendment. First, we determined that an officer did not maliciously and sadistically “knock[] [Mr.] Miller to the floor ” and “scuffle” with him after Mr. Miller had exited the law library without permission, resisted the officer’s handcuffing efforts, and “wrestled with [the officer].” Id. at 1564, 1567. On th e other hand, we found malicious and sadistic conduct where multiple officers later entered Mr. Miller’s holding cell and badly injured him by kicking, choking, beating a nd stomping him while he was restrained. Id.

7 See, e.g. , Lehman v. McKinnon , No. 20-1312, 2021 WL 4129229, at *1, *3 (10th Cir. Sept. 10, 2021) (unpublished) (determining that officer’s use of “[f]orce was surely necessary to overcome [inmat e’s] assault” where inmate had begun to comply with officer’s handcuffing order but then threw se veral punches and caused the officer to fall to the floor, where the inmate delivered several more blows); Tate v. Rockford , 497 F. App’x 921, 925 (11th Cir. 2012) (unpublis hed) (concluding that corrections “officers might have reasonably believed” it was nece ssary to use force to subdue inmate, including beating him and hitti ng him with handcuffs, where th e inmate had “recent prior violent behavior” against one of the officers, was yelling at the officers as they escorted him down a crowded hall, and then turned toward an officer); and Hughes v. Smith , 237 F. App’x 756, 759 (3d Cir. 2007) (unpublished) (indicati ng that force was necessary where inmate resisted office r’s entry into his cell and “s cuffl[ed]” with officer, who responded by p unching inmate and plac ing him in a headlock (quotations omitted)). Unpublished cases, even those from other circuits , can indicate that the law is not clearly established. See City and County of San Francisco v. Sheehan , 575 U.S. 600, 617 (2015) (suggesting that a “robust consensus of cases of persuasive author ity” showed that the federal right advanced by the plaintiff was not clearly established (quotations omitted)); Thompson v. Ragland , 23 F.4th 1252, 1260 n.3 (10th Cir. 2022) (observing that unpublished opinions “can be quite relevant in showing that the law was not clearly established” (quotations omitted)). Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 1314 The facts of Mr. Grissom’s case are much closer to the first Miller incident than the second. Officer Palm attempted to ha ndcuff Mr. Grissom for transit purposes and quickly found himself engaged in a violent fight where he needed to defend himself and regain control of the situation. As noted , we have not “identif[ied] a case where an officer acting under similar circumstances wa s held to have violated the [Eighth] Amendment.” District of Columbia v. Wesby , 138 S. Ct. 577, 590 (2018) (ellipsis and quotations omitted). Finally, we reject Mr. Grissom’s suggesti on that the “infringement of [his] rights [was] obvious.” Aplt. Br. at 5. Granted, “[g]eneral statements of the law can clearly establish a right for qualified i mmunity purposes if they appl y with obvious clarity to the specific conduct in question.” Halley v. Huckaby , 902 F.3d 1136, 1 149 (10th Cir. 2018) (quotations omitted). But we fail to see how Officer Palm’s use of the handcuffs and OC canister while attempting to subdue Mr. Gris som obviously qualifie s as “malicious[] and sadistic[]” uses of force, rather than “g ood faith effort[s] to maintain or restore discipline.” Redmond , 882 F.3d at 936. Because Mr. Grissom has not shown it wa s clearly established on November 25, 2017, that the force Officer Palm used was excessive, we conclude that qualified immunity applies. 8

8 Mr. Grissom contests qua lified immunity because K DOC found that Officer Palm violated its Internal Management Po licies and Procedures regarding the use of force. But such a finding is not dispositive on qualified immunity. See Groh v. Ramirez , 540 U.S. 551, 564 n.7 (2004) (noting that, standing alone, an official is not “deprived of qualified immunity whenever he violates an internal guideline”); Wilson Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 1415 Handcuffing We reach the same conclusion on Mr. Gri ssom’s handcuffing claim. He identifies no authority, and we have found none, clearly establishing that an officer’s attempt to apply regular-size handcuffs on an inmate w ho may need large-size handcuffs violates the Eighth Am endment. See Stevenson v. Cordova , 733 F. App’x 939, 946 (10th Cir. 2018) (unpublished) (finding no authority “i n this circuit or otherwise” clearly establishing that an officer violates the Eight Amendment by refusing to loosen a prisoner’s handcuffs).
Failure to Intervene Because we conclude it was not clearly es tablished that Officer Palm’s use of force was unlawful, it necessar ily follows that Officer Loewen did not have a clearly established obligation to int ervene to stop such force. See Ricciuti v. N.Y. City Transit Auth. , 124 F.3d 123, 129 (2d Cir. 1997) (observing that an officer “cannot be held liable in damages for failure to int ercede unless such failure permitte d fellow officers to violate a suspect’s clearly establishe d statutory or constitutional rights of which a reasonable person would have known” (quotations omitted)).

v. Meeks , 52 F.3d 1547, 1554 (10th Cir. 1995) ( observing that “violation of a police department regulation is insufficien t for liability under section 1983”). Appellate Case: 21-3194 Document: 010110726937 Date Filed: 08/19/2022 Page: 1516 III. CONCLUSION Because Mr. Grissom has failed to show a violation of a right that was clearly established, Officers Palm and Loewen ar e entitled to summary judgment based on qualified immunity. We affirm the district court’s judgment.
