Rule of Law:
When determining if an officer has reasonable suspicion for an investigatory stop under the Fourth Amendment, courts must evaluate the 'totality of the circumstances' rather than engaging in a 'divide-and-conquer' analysis of each individual factor.
Facts:
- Agent Clinton Stoddard, a border patrol agent, was working at a checkpoint on a remote highway in Arizona known for illegal immigration and smuggling.
- A magnetic sensor was triggered on Leslie Canyon Road, a rarely traveled, unpaved road often used by smugglers to bypass the checkpoint, during a time corresponding with the agents' shift change.
- Stoddard observed an approaching minivan, a vehicle type he knew smugglers often used. The driver, Ralph Arvizu, slowed dramatically, appeared rigid, and did not acknowledge the agent's presence.
- Stoddard saw that the children in the back seat had their knees raised unusually high, suggesting their feet were propped on cargo.
- As Stoddard followed the van, the children began to wave at him in a strange, mechanical pattern for four to five minutes.
- The minivan then made an abrupt turn onto Kuykendall Cutoff Road, a primitive dirt road that was the last available route to circumvent the checkpoint.
- A vehicle registration check revealed the minivan was registered to an address in a Douglas, Arizona neighborhood notorious for smuggling.
Procedural Posture:
- Ralph Arvizu was charged with possession with intent to distribute marijuana in the U.S. District Court for the District of Arizona.
- Arvizu filed a motion to suppress the marijuana evidence, arguing that the border patrol agent lacked reasonable suspicion for the vehicle stop.
- The District Court held a suppression hearing and denied Arvizu's motion.
- Arvizu appealed the District Court's decision to the U.S. Court of Appeals for the Ninth Circuit.
- The Ninth Circuit, as the intermediate appellate court, reversed the District Court, holding that the stop violated the Fourth Amendment.
- The United States petitioned the Supreme Court of the United States for a writ of certiorari, which was granted.

Issue:
Does a law enforcement officer have reasonable suspicion to conduct an investigatory stop of a vehicle when the officer's suspicion is based on a collection of behaviors, each of which is individually susceptible to an innocent explanation?
Opinions:
Majority - Chief Justice Rehnquist
Yes. A law enforcement officer has reasonable suspicion for an investigatory stop based on the totality of the circumstances, even if individual factors could have innocent explanations. The Fourth Amendment's reasonable suspicion standard requires courts to consider all factors together, through the lens of a trained officer, rather than evaluating and dismissing each factor in isolation. The Ninth Circuit erred by engaging in a 'divide-and-conquer analysis,' which is precluded by precedent such as Terry v. Ohio. Factors that are innocent by themselves, such as slowing down for a police car or a child's waving, can collectively amount to reasonable suspicion when viewed as a whole. The officer was entitled to draw on his experience and specialized training to make inferences from the cumulative information that might elude an untrained person, including the choice of a remote smuggling route, the timing during a shift change, the driver's demeanor, and the odd waving of the children.
Concurring - Justice Scalia
Yes. While joining the Court's opinion, this concurrence expresses skepticism about the standard of review itself. It questions the logical consistency of requiring an appellate court to conduct a de novo review, which implies a fresh look at the issue, while simultaneously instructing it to give 'due weight' to the factual inferences drawn by the trial judge. This creates a 'peculiar sort of de novo review' where the appellate court's independent judgment is constrained by deference to the lower court's conclusion on the very question of what constitutes suspicious behavior.
Analysis:
This decision significantly reinforces the flexible 'totality of the circumstances' standard for reasonable suspicion and serves as a strong rebuke to lower courts attempting to create rigid, categorical rules for evaluating individual factors. It solidifies the principle that the whole can be greater than the sum of its parts in a Fourth Amendment analysis. The case underscores the importance of deferring to an officer's experience-based inferences and makes it more difficult for defendants to challenge investigatory stops by arguing that each of their actions, viewed in isolation, was perfectly legal. It ensures that the reasonable suspicion standard remains a common-sense, non-technical concept based on the cumulative weight of all observations.
