Complex says: Police departments across the globe utilized the social network to create homepages in an effort to catch criminals. In March, an unnamed woman found her missing daughter on the site, 15 years after her husband made off with their two- and three-year-old kids. Florida police arrested the father on two counts of kidnapping and violating child-custody orders. Then, in September, a gang from Heaton, Newcastle made the mistake of posting images of themselves brandishing weapons and gloating about previous crimes they committed. Yeah, it didn’t take long before the cops logged on and arrested the juvenile perps. Stupidity at its finest.
