The United States Marshals Service reportedly is grabbing data from thousands, if not millions, of Americans' cellphones using high-tech devices deployed on five Cessnas. The aircraft operate out of at least five metro-area airports and apparently can cover most of the U.S. population. They are equipped with DRT boxes, popularly known as "dirtboxes," made by a subsidiary of Boeing. The DRT boxes gather the IMSI numbers -- a cellphone's unique identifier -- and geolocation data from all cellphones within their range.
