The courthouse seems to be a great place to find illegal aliens. They are clogging up our courts which are expensive to operate. Catapult them back over the border.
I'm not saying it was social media, but read the user agreements... most of them state that they will not require warrants when inquiries are made by law enforcement agencies.
Plus they just aren't that hard to data mine, plus no telling how many of those hot chicks and various humor pages or interest groups are actually run by law enforcement.
