The instances of U.S. law-enforcement agencies monitoring electronic communications such as phone calls, emails and even social network updates without a warrant has increased by as much as 60 percent in recent years, according to the American Civil Liberties Union.
The surveillance tools – known as either a “pen register” or a “trap and trace” – record such information as phone numbers and the time and length of calls, but not the content.
Orders to track phone calls increased 60 percent — from 23,535 in 2009 to 37,616 in 2011 — according to Justice Department documents, including ones recently acquired by the ACLU.
