How to charge my father for being violent?

Call the police(look up police department for your city, not 911). Let them know exactly what happened. Also make sure you have some proof or witness. If it was just a spanking, you have no case andspanking he has the right to do that, but if he like punched you in your face. You do. Although you would have deserved the spanking, kids need to be taught lessons for your own good so you will grow up to be good civilized people.
