 The Supreme Court is deciding not to hear a case over whether social media sites should be held responsible for what users say. Matt Mattinson has the story. It involves the Texas teen who was groomed by his science teacher over Snapchat. His family sued, saying the site enabled the abuse. Justice Clarence Thomas wanted it heard, and he wrote in dissent that the big tech firms are using Section 230 of the Communications Decency Act as a get-out-of-jail-free card.
