Break the law and your new 'friend' may be the FBI

The Feds are on Facebook. And MySpace, LinkedIn and Twitter, too. U.S. law enforcement agents are following the rest of the Internet world into popular social-networking services, going undercover with false online profiles to communicate with suspects and gather private information, according to an internal Justice Department document that offers a tantalizing glimpse of issues related to privacy and crime-fighting. Think you know who's behind that "friend" request? Think again. Your new "friend" just might be the FBI. The document, obtained in a Freedom of Information Act lawsuit, makes clear that U.S. agents are already logging on surreptitiously to exchange messages with suspects, identify a target's friends or relatives and browse private information such as postings, personal photographs and video clips. Among other purposes: Investigators can check suspects' alibis by comparing stories told to police with tweets sent at the same time about their whereabouts. Online photos from a suspicious spending spree–people posing with jewelry, guns or fancy cars–can link suspects or their friends to robberies or burglaries.
