United States v. Sokolow
The Supreme Court ruled that DEA agents had enough reason to briefly stop and question a traveler at Honolulu's airport, even though each individual fact about him -- paying cash, a quick round trip, nervousness, unchecked luggage -- was innocent on its own.
The decision approves the use of 'drug courier profiles' pieced together from ordinary travel behavior, holding that police can add up several innocent-seeming details to form a reasonable suspicion justifying a brief stop, even without any sign of an alias or evasive movement.
“Any one of these factors is not by itself proof of any illegal conduct and is quite consistent with innocent travel. But we think taken together they amount to reasonable suspicion.”
The Court's core holding that innocent facts can combine to create reasonable suspicion.
How it got here: A federal trial court denied Sokolow's motion to suppress the cocaine evidence; the Ninth Circuit reversed, and the government asked the Supreme Court to review that reversal.
The Case in Depth
What happened
Andrew Sokolow paid $2,100 cash for round-trip tickets from Honolulu to Miami under a name that didn't match his phone listing, stayed in Miami only 48 hours despite a 20-hour round trip, appeared nervous, and checked no luggage. DEA agents stopped him at the Honolulu airport, and a search eventually turned up over a kilogram of cocaine in his luggage, leading to his indictment for drug trafficking.
The question before the Court
Could DEA agents stop a traveler at the airport based on cash ticket purchases, a short trip, nervousness, and other everyday traits matching a drug courier profile?
Why it matters
Airline passengers can be briefly stopped and questioned by police based on a combination of common travel habits -- paying cash, short trips, unchecked bags, nervousness -- without any single one of those habits being suspicious by itself. The ruling gives law enforcement broader latitude to use behavioral profiles at airports, while critics warn it increases the chance that innocent travelers, especially those who fit stereotypes, will be stopped.
What changes now
The Ninth Circuit's ruling suppressing the evidence is reversed, and the case is sent back for further proceedings consistent with the Supreme Court's decision, meaning the cocaine evidence can be used against Sokolow. This is a final merits ruling on the reasonable-suspicion standard, not a temporary order, and it will guide how courts evaluate airport stops based on combinations of ordinary travel behavior going forward.
What this does not decide
The Court's holding was limited to the specific facts of Sokolow's stop and did not adopt a general rule that any combination of ordinary travel behaviors automatically creates reasonable suspicion. It also did not decide whether reliance on drug courier profiles is valid in all circumstances, only that using one here did not undercut the agents' suspicion.
Concurrences and dissents
Dissent — Justice Marshall
“Reflexive reliance on a profile of drug courier characteristics runs a far greater risk than does ordinary, case-by-case police work of subjecting innocent individuals to unwarranted police harassment and detention.”Marshall's central objection to the DEA's use of a drug courier profile.
Justice Marshall argued the facts known to the DEA agents -- nervousness, cash payment, a short trip, unchecked luggage -- described a huge category of innocent travelers and did not show ongoing criminal activity, unlike the true Terry-stop justification of stopping an imminent or ongoing crime. He criticized the drug courier profile as a 'chameleon-like' tool that adapts to fit any traveler and warned that mechanical reliance on such profiles dulls officers' judgment and risks harassing innocent people. He also argued the majority wrongly dismissed the relevance of using a profile and of the agents' failure to use less intrusive means before detaining Sokolow.
How the Court got there
The legal reasoning, step by step
- The Court applied the reasonable-suspicion standard from Terry v. Ohio, which lets police briefly stop someone based on specific, articulable facts suggesting criminal activity 'may be afoot,' a lower bar than the probable cause needed for an arrest or full search.
- The Court rejected the lower appeals court's rule that split evidence into a required category ('ongoing criminal activity,' like using a false name) and a lesser category ('personal characteristics' shared with innocent travelers), holding instead that all relevant facts must be weighed together under the totality of the circumstances.
- The Court reasoned that facts which are individually innocent -- paying cash from a large roll of bills, an unusually short round trip to a source city for drugs, nervous behavior, and unchecked luggage -- can still combine to create reasonable suspicion when considered together.
- The Court held that reliance on a 'drug courier profile' does not undermine an officer's suspicion, since a profile is simply a shorthand list of the same specific facts an officer must still be able to articulate.
- The Court also rejected the argument that agents were required to use the least intrusive method (like simply talking to Sokolow) before physically detaining him, reasoning that the reasonableness of a stop does not depend on whether a less intrusive alternative existed.

Distinguishes Reid v. Georgia (448 U.S. 438)
The Court found the facts known about Sokolow, while similar to Reid, together still amounted to reasonable suspicion unlike in Reid.

The Court relied on Terry's reasonable-suspicion standard as the governing test for brief investigative stops.
