Task: songer_const2

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the second most frequently cited provision of the U.S. Constitution in the headnotes to this case. Answer "0" if fewer than two constitutional provisions are cited. If one or more are cited, code the article or amendment to the constitution which is mentioned in the second greatest number of headnotes. In case of a tie, code the second mentioned provision of those that are tied. If it is one of the original articles of the constitution, code the number of the article preceeded by two zeros. If it is an amendment to the constitution, code the number of the amendment (zero filled to two places) preceeded by a "1". Examples: 001 = Article 1 of the original constitution, 101 = 1st Amendment, 114 = 14th Amendment.

TATE, Circuit Judge:
The defendant Sheikh appeals from his conviction, following trial by jury, on charges of (1) conspiracy to import heroin and to possess heroin with intent to distribute, in violation of 21 U.S.C. § 846 and § 963, and (2) possession of heroin with intent to distribute, in violation of 21 U.S.C. § 841(a)(1). We find the evidence insufficient to support the jury verdict of guilty on the conspiracy charge and, therefore, reverse the conviction on that charge. However, we affirm the conviction for possession with intent to distribute, finding no reversible error in the defendant’s contentions, inter alia, that severance of the trial with codefendants having antagonistic defenses was improperly denied, and that Fourth Amendment rights were violated by a customs search, 19 U.S.C. § 1582, at an airport port of entry (nearest the final destination of the goods, but not the first port of entry in the United States).
The Facts
On January 22, 1980, a crated package was shipped from Shiraz, Iran, by way of Iran Air, destined for delivery to Denton, Texas. The air waybill (or air consignment note) accompanying the crate listed as the shipper a Mr. Ahmad Javadzadeh and as the consignee a Mrs. Nasren Javadzadeh (“Nasren”). The package first arrived in the United States via Air France at the Houston Intercontinental Airport, was then transferred to American Airlines as per the air way bill, and was then transported by bonded carrier (a subsidiary of American Airlines) instead of by air, pursuant to arrangements made by American Airlines, to the Dallas-Fort Worth Airport (DFW) (the airport of final destination, per the waybill), where the package arrived on January 25, 1980. An American Airlines employee sent to the consignee letter notification of the arrival of the package. Meanwhile, the package remained in the American Airlines in-bond room, where international shipments were stored pending United States Customs inspection. (A primary fourth amendment contention made by the defendant is that although Houston — the airport where the shipment first landed — is a port of entry which is the functional equivalent of the border, the DFW airport — the final waybill destination, to which the goods were transhipped by the American airline to which the goods were transferred by Air France for final carriage to point of destination — cannot be considered as such.)
On January 29, 1980, a customs inspector at DFW opened the crate in order to examine the shipped items — a Koran and its display case. On close inspection, he discovered within the sides of the display case several secret compartments containing what was later determined to be 4.4 pounds of heroin. Drug Enforcement Administration (DEA) agents, who were immediately informed of the discovery, determined to prepare the display case for a controlled delivery. The heroin (except for a 14 gram sample that was returned to a hidden compartment of the display case) was removed from the secret compartments and replaced with Nestle’s chocolate. The plastic bags containing the substitute were coated with a powder that stains the skin an orange color on contact. DEA agents also installed in the display case a beeper device wired to emit rapid beeping sounds upon the opening of the hidden compartments.
On February 5,1980, Nasren, the consignee, picked up the crate and drove from DFW to her apartment in Denton, Texas (the address listed on the air waybill). At approximately midnight of February 6, 1980, DEA agents observed the arrival at the apartment of Hamid Javadzadeh Bijari (“Hamid”), Nasren’s brother. Approximately five minutes after his arrival, Ham-id left the apartment carrying the crate, and he put it in the trunk of his ear. DEA agents then followed him as he drove to a Sambo’s Restaurant in Denton, Texas, where he parked next to a Chevrolet Blazer and then entered the restaurant. Inside he met the defendant Sheikh, and the two returned to the restaurant parking lot. There, Hamid transferred the crate from the trunk of his car to the backseat of Sheikh’s Blazer. Both then entered their respective vehicles and returned to Nasren’s apartment.
At approximately 3:00 a. m. on the morning of February 7, 1980, Sheikh left the apartment and entered the Blazer (with the crate still inside) and headed toward Dallas. DEA agents followed Sheikh to a motel in Greenville, Texas. At no time prior to this stop did DEA agents within the range of the beeper detect a change from the slow beeping sound emitted by the beeper device to that of a rapid beep (which was to be triggered upon the opening of the secret compartments in the display case). Within minutes of his arrival at the motel room, Sheikh removed the display case (the shipping crate had been discarded in a dumpster at a stop en route) from the Blazer and took it inside his motel room. About two minutes later Sheikh returned to the Blazer, this time to remove a tool box. Soon after Sheikh re-entered the motel room, DEA agents detected a change in the slow beeper signal to that of a rapid beeping sound, an indication that the hidden compartments of the display case had been opened. Immediately thereafter, Sheikh exited the mote! room and headed toward the Blazer. However, DEA agents effected his arrest at the door of the Blazer before he could enter. Agents observed at the time of his arrest that Sheikh’s hands were stained the same orange color as the powder used to dust the plastic bags inside the secret compartments of the display case. Hamid and Nasren were arrested later the same day at Nasren’s apartment.
On February 21, 1980, a federal grand jury returned a two-count indictment charging that (1) on or about January 19 and February 7, 1980, Sheikh, Nasren, and Hamid conspired with each other and with others unknown to import heroin into the United States and to possess heroin with the intent to distribute (violations of 21 U.S.C. § 952(a) and § 841(a)(1)) in violation of 21 U.S.C. § 846 and § 963, and (2) on or about February 7, 1980, Sheikh knowingly and intentionally possessed with intent to distribute approximately 4.4 pounds of heroin, in violation of 21 U.S.C. § 841(a)(1).
All three co-indictees were tried together at a jury trial. The jury returned a verdict of guilty as to Sheikh on both counts and found Nasren and Hamid not guilty on the conspiracy charge, the only count upon which these eodefendants were charged. Sheikh was sentenced to ten years on both counts, with the terms to run consecutively. He was also assessed a special parole term of five years on both counts. Sheikh now appeals to this court for review of his convictions.
The Issues
The defendant Sheikh urges reversal of his convictions on the following contentions: (1) the trial court erroneously denied his motions for judgment of acquittal urged on the basis of the insufficiency of the evidence to support the jury verdict of guilty on the conspiracy charge; (2) the trial court erroneously denied his motions for severanee made both pre-trial and during the trial of the three defendants; (3) there was a significant variance between the amount of heroin Sheikh was charged with possessing as set forth in the indictment and the amount proven at trial to have been in his possession; (4) the trial court erred in admitting evidence obtained in violation of the defendant’s Fourth Amendment rights; and (5) the trial court violated his Sixth Amendment right to confrontation by its failure to conduct an inquiry to determine whether the codefendant Hamid justifiably asserted his Fifth Amendment privilege against self-incrimination.
1. The Conspiracy Charge
Sheikh and his codefendants Nasren and Hamid were charged in Count One of the indictment with conspiring with each other and with others unknown to import heroin and to possess heroin with intent to distribute. Sheikh was found guilty of the charged conspiracy despite the acquittal of Nasren and Hamid. Sheikh argues that the district court erred in denying his motions for judgment of acquittal in light of his codefendants’ acquittal and the insufficiency of the evidence to prove that he conspired with “others unknown.” We agree that a judgment of acquittal on the conspiracy conviction should have been granted based on the insufficiency of evidence to support the jury verdict and, therefore, reverse the judgment of conviction on Count One.
The general rule of this circuit is that the conviction of only one defendant in a conspiracy prosecution will not be upheld when all the other alleged coconspirators on trial are acquitted. United States v. Klein, 560 F.2d 1236, 1242 (5th Cir. 1977), cert. denied 434 U.S. 1073, 98 S.Ct. 1259, 55 L.Ed.2d 777 (1978); United States v. Peterson, 488 F.2d 645, 651 (5th Cir. 1974); United States v. Musgrave, 483 F.2d 327, 333 (5th Cir. 1973), cert. denied 414 U.S. 1023, 94 S.Ct. 447, 38 L.Ed.2d 315 (1973). However, a defendant may be convicted of conspiring with persons whose names are unknown or who have not been tried and acquitted, if the indictment asserts that such other persons exist, and the evidence supports their existence and the existence of a conspiracy. United States v. Klein, supra, 560 F.2d at 1242; United States v. Pruett, 551 F.2d 1365, 1369 (5th Cir. 1977); United States v. Lance, 536 F.2d 1065, 1068 (5th Cir. 1976); United States v. Pena, 527 F.2d 1356, 1365 (5th Cir. 1976), cert. denied 426 U.S. 949, 96 S.Ct. 3168, 49 L.Ed.2d 1185 (1976); United States v. Goodwin, 492 F.2d 1141, 1144-45 (5th Cir. 1974). In the instant case, with the acquittal of Sheikh’s two codefendants, the conspiracy conviction can only be upheld if there is sufficient evidence of the existence of an unnamed, unindicted coconspirator; the indictment (see note 2) having charged the three named defendants with having conspired with one another and “with others unknown” to import heroin from Iran and to possess it with intent to distribute it.
In reviewing the sufficiency of the evidence to support a jury determination of guilty, we are required to consider all the evidence in the light most favorable to the government. Glasser v. United States, 315 U.S. 60, 80, 62 S.Ct. 457, 469, 86 L.Ed. 680 (1942). Where the trial court has denied the defendant’s motion for judgment of acquittal, the evidence must be considered in the most favorable light to the government, in order to determine whether a reasonably minded jury could have concluded that the evidence was consistent with guilt and, in circumstantial evidence cases, inconsistent with every reasonable hypothesis of innocence. United States v. Marable, 574 F.2d 224, 229 (5th Cir. 1978); United States v. Caro, 569 F.2d 411, 416 (5th Cir. 1978); United States v. Pruett, supra, 551 F.2d at 1369; United States v. Barrera, 547 F.2d 1250, 1255 (5th Cir. 1977). We find that under the evidence a reasonably minded jury must have necessarily entertained a reasonable doubt as to Sheikh’s conspiring with “others unknown.”
The theory advanced by the government in support of the charged conspiracy with “others unknown” is essentially that Sheikh must have had a coconspirator since the package was shipped from Iran after Sheikh had left the country, and it was addressed to the same misspelled “Oake” Street address in Denton, Texas, as found under Nasren’s name in Sheikh’s address book. The following evidence appears in the record relevant to the proof of the existence of a coconspirator in Iran and of a conspiracy: (1) Sheikh knew a Nassir Alloi, who lived near Shiraz, Iran (the city listed on the air waybill as the shipper’s address and from which the package was sent) and whose telephone number was 21507 (the number given on the air waybill as the shipper’s); (2) while in Iran from late December of 1979 until January 17, 1980, Sheikh visited with Alloi; (3) Sheikh called Alloi from the United States on January 29, 1980 (the date that Sheikh became aware that the package addressed to Nasren had arrived at DFW); (4) in September of 1979, Alloi sent to Hamid as gifts three ornamental picture frames, one of which Sheikh expressed a particular interest in and took as his own; (5) in December of 1979, prior to his leaving for Iran, Sheikh made several calls to a number in Iran listed in Sheikh’s address book (directly under the listing for Nassir Alloi) as that of a Nassir Shirazy, who Sheikh claims is not the same person as Nassir Alloi.
The evidence proves at most that Sheikh had in Iran possibly two associates with whom he communicated prior to his trip to Iran, while in Iran, and after learning of the arrival of the package at DFW. Mere association between persons, however, cannot suffice as proof of a conspiracy. United States v. Fitzharris, 633 F.2d 416, 423 (5th Cir. 1980); United States v. White, 569 F.2d 263, 268 (5th Cir. 1978). Nor can suspicion, however strong, serve as proof of a conspiracy. Causey v. United States, 352 F.2d 203, 207 (5th Cir. 1965). While the government need not prove the existence of a formal agreement or otherwise rely on direct evidence to establish a conspiracy, see Hamling v. United States, 418 U.S. 87, 124, 94 S.Ct. 2887, 2911, 41 L.Ed.2d 590 (1974), it must do more than pile “inference upon inference” upon which to base a conspiracy charge. Causey v. United States, supra, 352 F.2d at 207. Rather, the government must prove beyond a reasonable doubt that the defendant and Alloi, or others unknown, knowingly entered into a conspiracy by which they agreed to import heroin into the United States and to possess it with intent to distribute. See United States v. Gutierrez, 559 F.2d 1278, 1280 (5th Cir. 1977); United States v. Barrera, supra, 547 F.2d at 1255.
Thus, while it is reasonable to speculate, as the government suggests, that Sheikh travelled to Iran to meet Alloi and arrange shipment of the heroin to the United States for distribution, and later called him to confirm that the heroin had been received as per their agreement, such speculation does not constitute proof beyond a reasonable doubt that the person in Iran knowingly agreed or conspired with Sheikh to perform acts with the intent to import heroin into the United States. See United States v. White, supra, 569 F.2d at 268. It is just as reasonable to infer from the evidence that while Sheikh was in Iran he made arrangements to have a person in that country mail to Nasren what the shipper believed to be only a Koran in a display case.
In the absence of evidence inconsistent with the latter hypothesis, or of any evidence from which the jury might infer a knowing agreement by the transhipper to participate in the importation of heroin into the United States, we must reverse the conspiracy conviction on the basis of insufficiency of the evidence. See, e. g., United States v. Fitzharris, supra, 633 F.2d at 422-23; United States v. Caro, supra, 569 F.2d at 416-19; United States v. White, supra, 569 F.2d at 267-68; United States v. Pruett, supra, 551 F.2d at 1368-69; United States v. Barrera, supra, 547 F.2d at 1256-57; United States v. Pena, supra, 527 F.2d at 1364-65.
2. The Severance Issue
At the trial below, Sheikh repeatedly urged — and was each time denied — his motion for severance first presented pretrial. The trial court’s denial of the motion, Sheikh insists, deprived him of his right to a fair trial. Specifically, Sheikh complains that he was subjected to trial alongside codefendants who asserted antagonistic defenses and who, in effect, aided the government in the prosecution of its case against Sheikh. While the issue raised presents an extremely close question of error, we cannot say — under the specific circumstances before us, and especially in light of the trial court’s actions taken to avoid possible prejudice to Sheikh — that he was denied a fair trial by the district court’s denial of severance.
The decision to grant or to deny a motion for severance rests within the sound discretion of the trial court, which will not be overturned on appeal without an affirmative showing of an abuse of discretion. Rule 14 of the Federal Rules of Criminal Procedure, providing for relief from joinder of defendants, has been interpreted to require that prejudice to the defendant attendant to a joint trial be balanced against the interests of judicial economy to determine whether severance ought to be granted. United States v. Garza, 563 F.2d 1164, 1166 (5th Cir. 1977), cert. denied 434 U.S. 1077, 98 S.Ct. 1268, 55 L.Ed.2d 783 (1978). The degree to which prejudice may be lessened by other remedial court action should also be considered. Id. Thus, the complaining party should be granted relief on appeal only upon a showing of compelling prejudice, which the trial court could not alleviate in the absence of severance and which effectively denied the party a fair trial. United States v. Horton, 646 F.2d 181, 186 (5th Cir. 1981); United States v. Mota, 598 F.2d 995, 1000 (5th Cir. 1979), quoting United States v. Swanson, 572 F.2d 523, 528 (5th Cir. 1978), cert. denied 439 U.S. 849, 99 S.Ct. 152, 58 L.Ed.2d 152 (1978).
Sheikh attempts to establish compelling prejudice in two respects. First, he claims that his defense at trial was antagonistic to the defenses asserted by his codefendants. Both Sheikh and the codefendant Hamid testified that they drove together in Sheikh’s Blazer from Panama City, Florida (where both lived) to Denton, Texas. Both testified that they rented a car at DFW which Hamid used to drive to Nasren’s to pick up the package while Sheikh remained at the Sambo’s Restaurant in Denton. Neither admitted, however, to having any knowledge of the existence of the hidden heroin or to having any reason to believe the other may have known of the heroin.
Despite the above consistencies, Sheikh contends that the thrust of the defenses was so antagonistic as to deny Sheikh a fair trial in the absence of severance. In essence, Sheikh represented at trial that (1) he agreed to take Hamid to Denton because he, Sheikh, wanted to try out his new Blazer and possibly visit friends in Houston, Texas; (2) it was Hamid’s idea to rent a car (used later to pick up the crated package from Nasren’s apartment) at DFW before going on to nearby Denton; (3) upon their arrival in Denton, it was Hamid who suggested that Sheikh wait at the Sambo’s Restaurant in Denton (where the package was transferred from the rented car to Sheikh’s Blazer) until Hamid returned from Nasren’s apartment (where Hamid picked up the package); and (4) the package belonged to Hamid, who asked Sheikh to take it back to Panama City. Furthermore, Sheikh testified that the envelope of lidocaine (used to cut down cocaine and heroin) found in Sheikh’s wallet at the time of his arrest was given to him by Hamid.
Hamid, on the other hand, testified that (1) he intended to visit Nasren long before he became aware of the existence of the package; (2) Sheikh admitted to having sent the package from Iran to Nasren’s address; (3) Sheikh said he sent packages from Iran to different addresses in the United States in order to insure that they were gotten out of the country successfully; and (4) it was Sheikh’s idea to rent the car for Hamid and then have Hamid pick up the package and meet Sheikh at the Sambo’s Restaurant. Hamid also denied having given Sheikh the envelope of lidocaine. The codefendant Nasren, consistent with her brother’s testimony, defended that it was her understanding that the package sent to her belonged to Sheikh..
The existence of antagonistic defenses among codefendants is cause for severance when the defenses conflict to the point of being irreconcilable and mutually exclusive. United States v. Horton, supra, 646 F.2d at 186; United States v. Marable, supra, 574 F.2d at 231. On appeal, however, the trial judge’s denial of severance may be reversed only on a showing that the defendant suffered “compelling prejudice.” United States v. Horton, supra, 646 F.2d at 186. In the instant case, the crux of the defense of each defendant was that he or she was ignorant of the existence of the heroin in the hidden compartments of the display case. To some extent, then, the defenses were not antagonistic. However, additionally each defendant contended that the crate containing the display case belonged to the other. Undoubtedly, in this respect, the defenses are so antagonistic as to be irreconcilable and mutually exclusive. Nevertheless, we do not find this antagonism sufficient under the particular facts to establish that Sheikh suffered the compelling prejudice that requires reversal of his possessory conviction because of the denial of severance. In so concluding, we emphasize that the essence of the defense of each codefendant — the absence of guilty knowledge — was not antagonistic with that of the other, and that no defendant indicated that he or she knew or believed the other to have had knowledge of "the existence of the heroin. To the contrary, Hamid testified that he had no reason to doubt the veracity of Sheikh’s explanation that it was necessary to send articles from Iran to various addresses in the United States in order to get them safely out of the former country. In addition, the evidence concerning Sheikh’s involvement with the shipments, summarized in our discussion of the sufficiency of the evidence to support the conspiracy conviction, together with the evidence concerning Sheikh’s actions in driving alone to Greenville with the package and, thereafter, in opening it, point so strongly to Sheikh’s possession that there was little, if any, actual prejudice to him in the joinder of his codefendants. The prejudice was to the codefendants, but they did not seek severance and were, indeed, acquitted.
The defendant Sheikh also attempts to establish compelling prejudice resulting from the denial of severance on the basis that his codefendants exhibited at trial an antagonistic attitude toward him. In effect, he claims that he was prosecuted not only by government counsel but also by counsel for Hamid and counsel for Nasren.
The taking of an adversarial stance on the part of counsel for codefendants may generate trial conditions so prejudicial to the codefendant under multiple attack as to deny him a fair trial. See United States v. Johnson, 478 F.2d 1129 (5th Cir. 1973); United States v. Valdes, 262 F.Supp. 474 (D.P.R. 1967). Considering the length of the trial (it lasted approximately three weeks) and the trial judge’s constant efforts to insure that the attorneys for Nasren and Hamid did not themselves act as prosecutors, we do not find that isolated instances of concerted attack as found in the trial court record created the sort of compelling prejudice necessary to warrant a severance.
In sum, after a careful review of the record, we are not left with a definite and firm conviction that the defendant Sheikh may have been prejudiced by the trial court’s refusal to grant the motion for severance made only by Sheikh. See 1 Wright, Federal Practice and Procedure: Criminal § 227 (1969). We reach this conclusion keeping in mind the view that in conspiracy cases persons jointly indicted should ordinarily be tried together. See United States v. Perez, 489 F.2d 51, 65 (5th Cir. 1973), cert. denied 417 U.S. 945, 94 S.Ct. 3067, 41 L.Ed.2d 664 (1974); 1 Wright, supra, § 223, but see id., § 226. In the face of possibly antagonistic defenses and hostility among codefendants, the trial judge properly and successfully lessened the degree of possible prejudice to Sheikh through careful trial supervision. Under these circumstances, Sheikh was not denied a fair trial.
3. The Variance Between the Indictment and the Evidence Presented at Trial
Sheikh asserts that the trial court erroneously denied his motion for judgment of acquittal on the possession with intent to distribute conviction, charged by Count Two, because of the significant variance between the allegations of that count of the indictment and the proof at trial. Count Two charged Sheikh with possessing, on or about February 7, 1980 (the date of his arrest), with intent to distribute, 4.4 pounds of heroin. At trial, the government proved that Sheikh was found in possession at the time of his arrest of 14 grams (i. e., about one-half ounce, but see note 9) of heroin (i. e., the amount retained in the display case hidden compartments from the original 4.4 pounds of heroin discovered pursuant to the earlier customs search). Although a variance may have existed, we reject the defendant’s contention that the variance is material or warrants a judgment of acquittal on the charge of possession of 4.4 pounds of heroin with intent to distribute.
Not every variance between the indictment and the proof is fatal to a conviction. In order for a variance to be fatal, thus mandating reversal, it must affect the substantial rights of the accused either (1) by insufficiently informing him of the charges against him such that he is taken by surprise and prevented from presenting a proper defense, or (2) by affording him insufficient protection against reprosecution for the same offense. United States v. Juarez, 573 F.2d 267, 278-79 (5th Cir. 1978), cert. denied 439 U.S. 915, 99 S.Ct. 289, 58 L.Ed.2d 262 (1978). See also Berger v. United States, 295 U.S. 78, 82, 55 S.Ct. 629, 630, 79 L.Ed. 1314 (1935); United States v. Lambert, 501 F.2d 943, 947-48 (5th Cir. 1974) (en banc). The defendant has failed to prove how the variance in proof of the amount of heroin actually possessed on the date of his arrest affected his substantial rights. There was no variance in proof as to the date of possession and substance possessed. Thus, in the absence of a showing to the contrary, we find the defendant was sufficiently notified of the crime charged to enable him to present a proper defense. Nor is there convincing argument made that the defendant could not successfully plead former jeopardy against reprosecution. We thus hold that the variance between the amount of heroin set forth in the indictment and the amount proved is not fatal and cannot form the basis for reversal of the conviction on Count Two.
Based upon the government’s failure of proof that Sheikh possessed the 4.4 pounds of heroin as charged in the indictment, Sheikh raises a subsidiary evidentiary issue. In particular, he urges as reversible error the trial court’s admission into evidence of testimony of (1) the street level dosage (generally found to be one to two percent pure heroin) equivalent in grams and pounds (96,214 grams or 212 pounds) of the 4.4 pounds of heroin (between 73%-76% pure) found in the display case during the customs search, and (2) the street value (ranging from $50-$100) of a gram of heroin at the street level dosage.
Evidence of the price or the quality of a narcotic possessed is generally relevant to prove intent to distribute. United States v. Palmere, 578 F.2d 105, 108 (5th Cir. 1978), cert. denied, 99 S.Ct. 1026, 439 U.S. 1118, 59 L.Ed.2d 77 (1979).
Thus, the street level dosage equivalent of the 4.4 pounds of heroin proved to have been imported into the United States from Iran was relevant to prove intent to distribute under the conspiracy count (Count One). Moreover, the testimony concerning the level of pure heroin generally found in a street level dosage was relevant to prove intent to distribute on the basis of possession of the 14 grams of heroin found to be 76% pure. The trial court’s admission of the testimony presents no reversible error.
4. The Alleged Fourth Amendment Violations
At trial, the defendant Sheikh objected to the introduction of evidence obtained as the result of (a) the warrantless customs inspection of the package at DFW, (b) the warrantless attachment and use of an electronic beeper inside the package, and (c) the warrantless search of the defendant’s motel room at the time of his arrest. On appeal, the defendant raises as reversible error the trial court’s admission of this evidence, alleged to have been obtained in violation of the defendant’s fourth amendment rights. We find no reversible error.
(a) The Customs Inspection at DFW
The substance of the defendant’s complaint as to the warrantless search at the DFW airport is: Since the air shipment had first entered the United States at the Houston airport port of entry before its transfer to the DFW airport port of entry, a customs search under 19 U.S.C. § 1582 (see note 10) (authorizing routine customs searches upon entry into the United States) was not authorized. Since therefore the search was not made at the functional equivalent of an international border but rather at an inland city to which the package had been shipped following entry into the United States, reasonable suspicion was required to justify the warrantless search. 19 U.S.C. § 482 (see note 14).
On January 29, 1980, customs inspector Cromer opened the crated package (containing the Koran, the display case, and the heroin) while it was stored in the American Airlines in-bound room, an area set aside by the carrier to house international freight that has not yet cleared customs. By way of this warrantless customs inspection, pursuant to which the 4.4 pounds of heroin was discovered, the DEA investigation was set in motion which ultimately led to the defendant’s arrest. Sheikh attempted by a motion to suppress to prevent the government’s introduction of the heroin thus obtained. The trial court denied the defendant’s motion on the basis that the warrantless inspection was authorized by 19 U.S.C. § 1582, 19 C.F.R. § 162, providing for warrantless customs searches of persons, baggage, and merchandise coming into the United States. We agree.
Warrantless searches made at the international borders of the United States are considered reasonable under the Fourth Amendment simply by virtue of the fact that they occur at the border. United States v. Ramsey, 431 U.S. 606, 616-20, 97 S.Ct. 1972, 1978-80, 52 L.Ed.2d 617 (1977). Moreover, routine border searches may be conducted regardless of whether customs officials have a reasonable or articulable suspicion that criminal activity is afoot. United States v. Chaplinski, 579 F.2d 373, 374 (5th Cir. 1978), cert. denied, 439 U.S. 1050, 99 S.Ct. 731, 58 L.Ed.2d 711 (1978); United States v. Himmelwright, 551 F.2d 991, 993-994 (5th Cir. 1977), cert. denied, 434 U.S. 902, 98 S.Ct. 298, 54 L.Ed.2d 189 (1977). See also Carroll v. United States, 267 U.S. 132,154, 45 S.Ct. 280, 285, 69 L.Ed. 543 (1925). We have held that 19 U.S.C. § 1582 provides statutory authorization for warrantless border searches by customs officials of all persons, baggage, and merchandise entering the United States. United States v. Pringle, 576 F.2d 1114, 1116 (5th Cir. 1978). The warrantless border searches do not require either probable cause or individualized suspicion of criminal activity. Id. See also United States v. Scheer, 600 F.2d 5, 7 (3d Cir. 1979); United States v. Odland, 502 F.2d 148, 151 (7th Cir. 1974).
The applicability of § 1582 in the case before us thus depends upon whether, for purposes of the warrantless search by the customs officer of the package originating outside the United States, DFW can be considered an international border or its functional equivalent.
The functional equivalent of an international border includes, by way of example, the United States airport that serves as the destination for a nonstop flight from a foreign point. Almeida-Sanchez v. United States, 413 U.S. 266, 272-73, 93 S.Ct. 2535, 2539, 37 L.Ed.2d 596 (1973); United States v. Himmelwright, supra, 551 F.2d at 993-94. Such an airport is considered the functional equivalent of a border because of (1) the existence of reliable indications that the thing to be searched is of international origin and has not been changed in any way since entering the United States; and (2) the degree of regularity with which searches at the point in question are conducted such that the intrusion is minimal, the existence and function of the checkpoint are known in advance, and there is little discretionary enforcement activity. United States v. Brennan, 538 F.2d 711, 715-16 (5th Cir. 1976). For these same reasons, we consider DFW, under the circumstances here presented, the functional equivalent of a border.
. [20] In the instant case, the air waybill accompanying the package indicated that it was sent from Iran by way of Iran Air. The waybill issued by Iran Air stated the airport of final destination was Dallas DFW, also indicating intermediate transfers at Paris (where it was to be transferred to Air France), and Houston (where Air France was to transfer it to American Airlines for final transit to Dallas DFW airport). The package first arrived in the United States on January 24, 1980, via Air France at the Houston Intercontinental Airport. It was immediately transferred from that Houston freight terminal to the American Airlines freight terminal. American Airlines then shipped the package by truck to its freight terminal at DFW. At all times after the package entered the United States until it was searched at DFW by customs inspector Cromer it remained under a United States customs bond. Prior to the January 29,1980 search at DFW, the package had not cleared customs, and the evidence negatives any indication it had been tampered with. Thus, the evidence shows reliable procedures to insure that the package came from a foreign point and remained in the same condition until an actual customs inspection could be made. (In this case, the customs inspection developed into a customs search.) Additionally, since DFW is itself an international port of entry, foreign shippers are put on notice that a package passing through that airport will be subject to a routine customs search, if it has not previously been subject to customs inspection. A customs official testified that under customs procedures the port of

Question: What is the second most frequently cited provision of the U.S. Constitution in the headnotes to this case? If it is one of the original articles of the constitution, code the number of the article preceeded by two zeros. If it is an amendment to the constitution, code the number of the amendment (zero filled to two places) preceeded by a "1". Examples: 001 = Article 1 of the original constitution, 101 = 1st Amendment, 114 = 14th Amendment.
