A Customs and Border Protection officer checks IDs as people enter the US from Mexico in San Ysidro, California. Do I have the same legal rights at the border that I would elsewhere? The Fourth Amendment, which protects people from searches and seizures without probable cause of a crime being committed, doesn't apply in the same way at the border, Rizzo said. An air traveler is cleared by a Customs and Border Protection Officer at Dulles International Airport outside Washington. "If you don't want it searched, don't carry it across the border," Rizzo says.
