If a federal judge in Kansas issues a wiretapping order to federal law enforcement, can they rely on that order when the target travels to another state? Or rather, if law enforcement neglects to get a new order from the new state, is the evidence admissible?
Search warrants are generally required when police officers search your property -- unless a specific exception applies. In 1925, the U.S. Supreme Court carved out a major exception to the search warrant requirement in a case called Carroll v. United States. It created the "automobile exception" or "motor vehicle exception," which essentially allows any motor vehicle to be searched without a warrant as long as the officer has probable cause to believe that evidence or contraband will be found in that vehicle.
