Police have charged Carlos Anthony Hollins after they say he used social media to make a threat of violence against an entire Maryland town. The message was uncovered Wednesday afternoon when La Plata Police were alerted to a post on Twitter that read, “IM NOT GONNA STAND FOR THIS NO. MORE. TONIGHT WE PURGE! KILL ALL THE WHITE PPL IN THE TOWN OF LA PLATA.” That tweet sparked a massive police effort and the man accused of sending the tweet was tracked down and arrested.
