People know people. It's how Facebook works. Now it's a random force for good, helping to track and convict a thief in Birmingham in the UK. Omar Famuyide was spotted on the social network's "people you may know" feature by one of his victims, after which UK police connected him to multiple robberies and firearms offenses. The BBC reports that he was jailed for 17 years for robbery, attempted robbery, possession of a firearm and possession of a knife.
