“Section 206 of the Patriot Act [signed into law on October 26, 2001]… amends the 1978 Foreign Intelligence Surveillance Act, which, in part, required intelligence agents to obtain separate court orders to monitor each telephone, computer, or other communication facility. Section 206 permits ‘roving wiretaps,’ which, in the words of [President Bill Clinton’s Chief of Staff John] Podesta, allows officials to ‘tap the person rather than the phone.’ The problem here is that surveillance targets can and do use public communications of ordinary Americans, without, as the Fourth Amendment requires, a search warrant that ‘particularly describe[s] the place to be searched.’ ”
