And it's easy to see why: While it helps that you share 'enormously detailed information' online, it's your social network that really does the talking, says Lee Altschuler, a Federal defense attorney. 'Cops will figure out who the associates of the suspect are,' Altschuler explained. 'The police will then friend or connect to the associates, working to gain their trust, and then will eventually friend the target directly, or be able to glean information about the target through the associates.' Of course, this is pretty much the same action they've always taken in the offline world, it's just far more efficient on social media (plus, there's the aforementioned willingness to share information online)."
