The Supreme Court on Monday handed another Fourth Amendment defeat to police, ruling that a Border Patrol officer’s “squeeze search” of a bus passenger’s soft luggage was an unreasonable intrusion into personal privacy.

It was the second decision favoring defendants in a search and seizure case in less than a month. On March 28, the Court said in Florida v. J.L. that an uncorroborated anonymous tip that a person was carrying a gun was not enough to justify a police search.
