Assault. He ripped the reg out of my mouth. The funny part? He contacted the Ranger complaining about me. The Ranger came up to me and was starting to give me the third degree in front of my class. When I pointed out what he had done, the ranger asked him "Is this true?" They guy said yes, and the Ranger hand cuffed him there on the spot and led him off. The class clapped as they walked off with the guy protesting his innocence.
I have no idea if charges were filed.
