A University of Central Florida student was shot by officers with a Taser after going on a shirtless rant during an apparently bad LSD trip, an incident caught on police body cameras. John Cain, 21, had pulled the fire alarm at UCF’s library Sunday and ran outside yelling for help when fellow students tried to calm him. As the students waited for campus police to arrive, witnesses were heard on the video saying Cain told them he took LSD and needed help. He also kept removing his clothing. When officers arrived, body cameras showed them confront a shirtless Cain, who put up a brief fight before he was shot with the Taser and taken into custody.
