The vast majority of law enforcement wiretaps in 2011 were for telephones (including mobiles) and only a tiny percentage included encryption, which in no case prevented officials from obtaining the plain text of the communications.
That's according to the latest annual U.S. Courts report on wiretapping by federal and state government-authorized wiretaps.
Of the 2,189 court-ordered intercepts, 95.6 percent of the 2,189 total were for some type of telephone, whether a plain old one, a cell phone or another type of mobile device. Only four were against some type of electronic device, including a digital pager, fax or computer. Another six were for oral communications (intercepted with a microphone) and 87 were for a combination of more than one intercept type. (more)
