Navarette v. California

Docket No. 12-9490


1. Does the Fourth Amendment require an officer who receives an anonymous tip regarding a drunken or reckless driver to corroborate dangerous driving before stopping the vehicle?

2. Does an anonymous tip that a specific vehicle ran someone off the road provide reasonable suspicion to stop a vehicle, where the detaining officer was only advised to be on the lookout for a reckless driver, and the officer could not corroborate dangerous driving despite following the suspect vehicle for several miles?
