I am sorry to hear that, Shay. For what it is worth, confronting him is the worst idea. The guy is violent and has the potential to go off and hurt anyone who tries to tell him he is mistreating his child. And telling him this will not change his behavior. You have already tried that and he didn't care. I understand why you feel upset. They all agreed to do something and now are backing out. What you may want to try is reporting this to the authorities just as you planned. Then let them know there are other witnesses. Give them the names of who was there. And let the police handle it from there. You do have a lot of evidence to back up what you are saying so that will be enough.
