Fox News:  U.S. law-enforcement agencies are increasingly obtaining warrants to search Facebook, often gaining detailed access to users’ accounts without their knowledge.

A Reuters review of the Westlaw legal database shows that since 2008, federal judges have authorized at least two dozen warrants to search individuals’ Facebook accounts. Many of the warrants requested a laundry list of personal data such as messages, status updates, links to videos and photographs, calendars of future and past events, “Wall postings” and “rejected Friend requests.”
