Is the Whole Country an Airport Security Zone?
Full-body scanners in roving vans:
American Science & Engineering, a company based in Billerica, Massachusetts, has sold U.S. and foreign government agencies more than 500 backscatter x-ray scanners mounted in vans that can be driven past neighboring vehicles to see their contents, Joe Reiss, a vice president of marketing at the company told me in an interview.
This should be no different than the Kyllo case, where the Supreme Court ruled that the police needed a warrant before they can use a thermal sensor on a building to search for marijuana growers.
Held: Where, as here, the Government uses a device that is not in general public use, to explore details of a private home that would previously have been unknowable without physical intrusion, the surveillance is a Fourth Amendment “search,” and is presumptively unreasonable without a warrant.
