United States v. Clifton Mosley

Plain English (For Everyone)

Imagine a police officer gets a tip about a car and driver involved in a crime. The court said that if the tip is reliable enough, the officer can pull over the car to investigate. In this case, the tip was reliable, so the stop was legal. Even after stopping the car, the officer asked questions related to the initial reason for the stop, and when they found illegal items, it was allowed because the stop itself was proper.

For Legal Practitioners

The Fourth Circuit affirmed the denial of a motion to suppress, holding that a BOLO alert from another jurisdiction, corroborated by the officer's observations, established reasonable suspicion for the traffic stop. The court also found that the scope of the stop was not unlawfully expanded, as the officer's questioning was germane to the initial stop's purpose and the discovery of contraband was a lawful consequence. This decision reinforces the validity of BOLO alerts as a basis for reasonable suspicion and provides guidance on permissible scope expansion during traffic stops.

For Law Students

This case tests the Fourth Amendment's reasonable suspicion standard for traffic stops based on BOLO alerts. The court found the BOLO sufficiently reliable, establishing reasonable suspicion. It also addressed the scope of a lawful traffic stop, determining that questions related to the initial stop and subsequent discovery of contraband were permissible. This case is relevant to the doctrines of investigatory stops (Terry stops) and the exclusionary rule.

Newsroom Summary

The Fourth Circuit ruled that police can stop a vehicle based on a reliable 'be on the lookout' alert, even if the alert originated from another jurisdiction. This decision impacts individuals pulled over by police, as it broadens the grounds for lawful traffic stops and subsequent searches if contraband is found.

Procedural Posture

The defendant, Clifton Mosley, was convicted of federal drug and firearms offenses. He appealed his conviction, arguing that the district court erred in denying his motion to suppress evidence obtained during a traffic stop. The Fourth Circuit reviewed the district court's denial of the motion to suppress.

Constitutional Issues

Fourth Amendment - protection against unreasonable searches and seizuresWhether the traffic stop was supported by reasonable suspicion

Rule Statements

"A traffic stop is a seizure within the meaning of the Fourth Amendment, and therefore must be reasonable."

"Reasonable suspicion exists when an officer has 'a specific and articulable fact, which, taken together with rational inferences from those facts, reasonably warranting the intrusion.'"

Scenario: You are driving and are pulled over by a police officer who says they received an alert about your car being involved in a crime. The officer asks you questions related to the alert and then searches your car, finding illegal items.

Your Rights: You have the right to know why you were stopped. If the stop was based on a reliable alert and the officer's questions were related to the reason for the stop, the stop and any subsequent discovery of illegal items may be considered lawful.

What To Do: If you are stopped, remain calm and ask the officer for the reason for the stop. Do not consent to a search of your vehicle unless the officer has probable cause or a warrant. If illegal items are found and you believe the stop or search was unlawful, you have the right to challenge the evidence in court.

Is it legal for police to stop my car based on an alert from another police department?

Yes, it can be legal if the alert is considered reliable and provides the officer with reasonable suspicion that your vehicle is involved in criminal activity. The court will look at the specifics of the alert and how it was corroborated.

This ruling applies to the Fourth Circuit, which includes Maryland, North Carolina, South Carolina, Virginia, and West Virginia. Other jurisdictions may have similar or different standards.

For Drivers

Drivers may be subject to traffic stops based on 'be on the lookout' (BOLO) alerts issued by law enforcement agencies. This ruling makes it more likely that evidence found during such stops will be admissible in court, potentially leading to increased enforcement actions.

For Law Enforcement Officers

This decision provides clear guidance that BOLO alerts, when sufficiently reliable and corroborated, can form the basis for reasonable suspicion to initiate a traffic stop. It also clarifies that questioning related to the initial stop and discovery of contraband during a lawful stop are permissible.
