Bad news if you're a drug dealer or murderer or some sort of sex criminal: a judge just ruled your "friends" can show cops your Facebook profile. And then you can go to jail, GigaOm reports. Time to start deleting!

The ruling, handed down by US District Judge William Pauley III, showed that a suspect in question had no 4th Amendment protection against Facebook peeping, if his friends ratted him out. Which is exactly what happened to one Miami fellow who made gang-related threats on his Facebook profile. Unfortunately for him, his "legitimate expectation of privacy ended when he disseminated posts to his 'friends' because those 'friends' were free to use the information however they wanted—including sharing it with the Government." All it takes for your Timeline to be evidence is a friend to show a cop an LCD screen.
