Re: Orin Kerr

Orin Kerr was quoted about a case before the U.S. Supreme Court that decided whether cell phone records could be obtained by the federal government without a warrant. According to Kerr, the government’s case relied on older cases stemming from the 1970s when technology was inferior to today’s wireless and heavily interconnected world.
