Opinion for the Court filed by Circuit Judge SENTELLE.
Orlando Caicedo-Llanos appeals his conviction for possession of over 500 grams of cocaine with intent to distribute. He argues that the government’s failure to preserve and produce certain photographic evidence violated his due process rights under
Brady v. Maryland,
I. Background
A. Facts
Consistent with the findings of the District Court, the facts of this case are as follows. The New York City Police Department (NYPD) telephoned Detective Dade of the Metropolitan Police Department’s Fugitive Squad on January 16,1990, seeking assistance in apprehending two suspects wanted in connection with a double shooting. 1 The NYPD informed Detective Dade that both suspects were male, black, and Panamanian. It also informed him that the two were travelling together on a bus scheduled to arrive in Washington, D.C., later that day. The NYPD provided Dade with the arrival time, the gate, and the number of the bus. It also offered him the name and a description of one suspect, and the name and illegal alien status of the other. In addition to the information provided by telephone, the NYPD faxed Dade a photograph of one suspect. Based on the telephoned and faxed information, officers of the Metropolitan Police Department obtained the assistance of Immigration and Naturalization Service (INS) Special Agent Crispino, and arrived at the bus station ahead of the bus described by the NYPD.
As Dade and Sergeant Getz, also of the Metropolitan Police Department, watched passengers disembark from the bus, they noticed a man who, in their opinion, matched the description of the subject mentioned in the telephone call and pictured in the faxed photograph. This individual was later identified as Mr. Palamino-Perez (the “codefendant”). Sergeant Getz approached and asked the codefendant questions, but could not communicate with him: Palamino-Perez speaks only Spanish. At this point, INS Agent Crispino approached, showed his badge, and, speaking in Spanish, asked Palamino-Perez his name, place of birth, and whether he had any identification or immigration papers with him. Pa-lamino-Perez responded that he was born in Colombia, lived presently in New York, and had no form of identification or immigration papers. Palamino-Perez was arrested for violating immigration laws and then searched.- Getz found two kilo bricks of cocaine in a girdle strapped to the code-fendant’s body.
Simultaneous with the questioning of Pa-lamino-Perez, Officer Fant, another Metropolitan Police officer, boarded the bus and noticed another individual he thought fit the description of the wanted suspects. This individual, Mr. Caicedo-Llanos (the “appellant”) was apparently fumbling with something under his seat. A woman on the bus told Fant that. Caicedo-Llanos “put it under his seat.” Fant then apparently got off the bus to speak with the bus driver; the driver told him that the code-fendant and appellant had travelled together. At this point, Fant also learned of the *160 codefendant’s arrest and of the cocaine recovered from his girdle. Gun drawn, Fant reboarded the bus, conducted a pat-down of Caicedo-Llanos, and led him off the bus. Crispino then questioned appellant about his immigration status and learned that he too was born in Colombia and had no immigration papers. Crispino arrested Caicedo-Llanos for violating immigration laws and then conducted a search. Crispino found two kilos of cocaine strapped to Caicedo-Llanos’ body. Police also recovered the package under Caicedo-Llanos’ bus seat at this time and found it filled with cocaine. The apparent street value of the drugs recovered from appellant and codefendant was $806,040.
Following the arrests, all copies of the photograph faxed from the NYPD were lost or discarded. Dade testified at a suppression hearing that he could not recall who at the NYPD sent the fax to him, or in which New York office the sender worked. A copy of the fax sat on Dade’s desk for several months, but he discarded it one week before the prosecutor contacted him about the case. Dade is a twenty-year veteran of the Metropolitan Police. 2
At trial, varying descriptions of the faxed photograph were elicited from the various officers involved in appellant’s arrest. Officers disagreed as to whether the picture depicted one or two men, and whether the man (or men) depicted wore facial hair or a long haircut. Defense produced the bus driver, Mr. Walter Clay, who testified that police had shown him the faxed photograph and that he told them he had seen no resemblance between the picture and either the appellant or codefend-ant. Clay did, however, acknowledge that Palamino-Perez and Caicedo-Llanos had boarded the bus and travelled together.
The government conceded at trial that appellant is not one of the New York shooting suspects. Defense counsel apparently acknowledged that appellant is an illegal alien, that he is a black Hispanic male, and that he was travelling with Palamino-Per-ez.
B. Hearing Before the District Court
1. Appellant’s Position
Appellant and codefendant argued in the District Court that, under
Brady v. Maryland,
Appellant and codefendant argued that the proper remedy for the photograph’s loss was suppression of all evidence recovered in both arrests. Such a suppression, they continued, would of course necessitate a dismissal of the charges against them.
2. The District Court’s Ruling
The District Court ruled that the due process issue in this case should not be analyzed under
Brady,
but under
Arizona v. Youngblood,
Applying Youngblood, the trial court concluded that the police had not acted in bad faith. It also noted that the photographic evidence was immaterial to appellant’s defense because the police could have properly arrested and searched appellant, even if the photograph had been available and looked nothing like codefendant: first, Officer Fant had probable cause to arrest appellant based on his belief that Caicedo-Llanos was one of the two fugitives travelling together and his knowledge *161 that drugs had been recovered from the codefendant; second, Fant had sufficient articulable suspicion to stop appellant to investigate whether he was one of the two fugitives and, after appellant was taken off the bus, the INS Agent had probable cause to arrest him for immigration violations.
Appellant now contends on appeal that the District Court erred in applying Young-blood rather than Brady and that, under either standard, a due process violation occurred which requires the suppression of all seized evidence. He also alleges that the government violated his discovery rights under Fed.R.Crim.P. 16.
II. Analysis
A. Due Process Concerns
1. Appellant’s Argument
Appellant contends that the District Court erred in applying
Youngblood
rather than
Brady
to the facts of this case.
Youngblood
is inapplicable, he argues, because the faxed photograph is not evidence “of which no more can be said than that it could have been subjected to tests, the results of which might have exonerated the defendant.”

2. The Materiality Requirement and the Personal Nature of the Fourth Amendment Guarantee
While the question of which due process standard should apply to the facts before us raises interesting constitutional issues, it is one we need not resolve today. Under either
Youngblood
or
Brady,
appellant is obliged to demonstrate that the evidence he seeks is in some fashion material to his defense.
See Brady,
Appellant’s materiality argument follows this course:
Fant [arrested Llanos] when he was told that Llanos had gotten on the bus with Perez, who had been stopped and searched assertedly because of his resemblance to the missing FAX. It is thus clear that Llanos’ arrest flowed, in fact, from the arrest of Perez, which was legal only if Perez resembled the FAX.
Appellant’s Initial Brief at 16. According to appellant, then, the photograph is material to his defense only because of its value in challenging the validity of his codefend-ant’s arrest, from which his own search “flowed.”
The problem with appellant’s syllogism lies not in its chain of inference and argument, but in its fundamental assumption. At bottom, it rests on the proposition that appellant may argue for the suppression of evidence recovered in another person’s search. More plainly: it assumes that appellant may assert the Fourth Amendment rights of his codefendant. Without this assumption as analytical bulwark, appellant’s entire materiality syllogism must fall.
Our Fourth Amendment jurisprudence is very clear in its rejection of appellant’s fundamental assumption: it does not countenance the assertion of another’s
*162
right to be free from unreasonable searches and seizures. Fourth Amendment rights are emphatically “personal rights which, like some other constitutional rights, may not be vicariously asserted.”
Alderman v. United States,
If appellant could show that the photograph was used as the basis for his own arrest, we might have a substantially different case before us. But, as the facts show, and appellant concedes, the photograph is material only to determining the validity of another person’s arrest, not his own. Consequently, it is completely irrelevant to his defense.
Appellant resists this conclusion with three points. First, because the government did not challenge his capacity to assert the codefendant’s Fourth Amendment rights before the District Court, appellant argues that it is precluded from doing so on appeal. He is correct to point out that “an appellate court does not give consideration to issues not raised below,” as litigants ought not to be “surprised on appeal by final decision there of issues upon which they ha[d] no opportunity to introduce evidence.”
Hormel v. Helvering,
An inescapably “particular circumstance” exists here. The personal nature of the Fourth Amendment guarantee is a substantive limit on the rights of the individual: we are powerless to rule on Fourth Amendment rights which do not belong to the parties before us. Further, appellant cannot convincingly complain that he is the unfortunate litigant for whom the rule against sandbagging was designed.
Hormel,
We note that the First Circuit has faced this issue and decided it as we do.
United States v. Miller,
Finally, we acknowledge that on one occasion the Supreme Court did preclude argument about the scope of a defendant’s Fourth Amendment rights because the issue had not been raised below.
See Steag-
*163
ald v. United States,
At no point in the case before us has the government affirmatively represented that Caicedo-Llanos may raise a Fourth Amendment claim to Palamino-Perez’s person. At best, it can be said to have acquiesced in appellant’s own assertion that he had a cognizable interest in the codefendant’s arrest. We decline to hold that mere acquiescence is enough to preclude the government from raising Fourth Amendment concerns for the first time on appeal. Our position is in harmony with the Tenth Circuit’s treatment of this issue.
See Hansen,
Second, appellant claims that, at the very least, this Court should remand this case to the District Court for further proceedings to explore his rights in codefendant’s person. In
Combs v. United States,
Further, the issue before the Court in
Combs
involved appellant’s expectation of privacy in a particular geographic location — a question of fact and, thus, properly the domain of the trial court. Here, however, the question before us is not appellant’s expectation of privacy in a certain location, but in another person — an issue of law, not fact — and thus, one amenable to our scrutiny. We note that the Tenth Circuit has also distinguished
Combs
along the lines we do.
See Hansen,
Appellant’s final objection rests on a single case from the Eastern District of New York which, he argues, established that he may assert his codefendant’s Fourth Amendment rights. In
United States v. Westerbann-Martinez,
We also note that
Westerbann-Martinez
is probably not the law even in the circuit where it was decided,
see United States v. Riquelmy,
3. Other Materiality Issues
There may be materiality problems lurking in appellant’s claim to the faxed photograph beyond the Fourth Amendment difficulty we have identified. As mentioned above, the trial court assumed that even if appellant had a legitimate expectation of privacy in his codefendant’s person and even if that expectation were impermissibly violated, there were still alternative bases for finding the faxed photograph immaterial for due process purposes. We think it unnecessary to reach these additional materiality arguments, however, having demonstrated that the only use to which appellant *164 might put the photograph is plainly impermissible. 3
B. The Rule 16 Argument
Appellant claims that, even if the photograph’s loss does not implicate his due process rights, it does violate his discovery rights. Under Fed.R.Crim.P. 16(a)(1)(C), a defendant may, on request, compel disclosure of information “material to the preparation of [his] defense.” Appellant, however, failed to include this argument in his initial brief; instead, he relegated it to two paragraphs in his reply brief.
This Court will not ordinarily entertain arguments inadequately briefed on appeal.
See Carducci v. Regan,
Finding no extraordinary reason to avoid the application of our general rule, we decline to consider appellant’s Rule 16 claim. 4
III. Conclusion
Appellant must show that the evidence he seeks is, in one fashion or another, material to his defense. Because his only theory on the materiality of the faxed photograph falters in assuming that he may assert another’s Fourth Amendment rights, appellant’s conviction is
Affirmed.
Notes
. In proceedings before the District Court and its brief to this Court, the government represented the incident for which the two suspects were wanted as a "double homicide.” Only at oral argument before this Court did the government state for the first time that the incident was a "double shooting” which may or may not have resulted in death. We should hope that the government might become more careful in its representations.
. We should hope that a Metropolitan Police veteran of twenty years would be trained to retain information such as the faxed photograph and the name of his New York contact.
. We do note that even if appellant could overcome his Fourth Amendment difficulties, the faxed photograph would
still
be immaterial for Fifth Amendment due process purposes. The trial court found that Caicedo-Llanos' arrest could be sustained without any reference to the missing fax on three alternative grounds: (1) a stop pursuant to
Terry v. Ohio,
. We do note that even if we were to consider the Rule 16 argument, it is not a compelling one. While the materiality requirement in the discovery rules may differ slightly from the materiality requirement in the due process scenario, it still requires a showing that
the evidence in question bears some abstract logical relationship to the issues in the case.... There must be some indication that the pretrial disclosure of the disputed evidence would have enabled the defendant significantly to alter the quantum of proof in his favor.
United States v. Ross,
For reasons discussed above in the due process context, the faxed photograph could not meet this standard.
