Which 2014 US Supreme Court case allowed a DWI stop after a frantic 911 call?

The 2014 Supreme Court case that permitted a DWI stop based on a frantic 911 call is Navarrette v. California. In this case, the Court ruled that law enforcement officers could initiate a traffic stop based on information provided by a 911 caller, especially when the call indicated erratic driving behavior that posed a potential threat to public safety. The context of the call and the urgency of the situation contributed to the court’s determination that the officers had reasonable suspicion to act.

This decision highlights the balance between the need for public safety and the standards required for police action. When a 911 call is made, particularly one that expresses urgent concerns regarding someone's dangerous driving, it provides law enforcement with a reasonable basis to investigate further. The Court's ruling underscored that anonymous tips, when corroborated by the officer’s own observations, can form a legitimate basis for a traffic stop.
