Your tone is vindictive. Give him his belongings back. It's not your role to withhold firearms simply based on your personal opinion he shouldn't have the right to them. That's for law enforcement and the criminal court system to judge, not you. If you feel unsafe, request a protective order. Your daughter has a name. Don't take that from her because of you personal resentment. You've got his money - be content with that. It sounds like you should seek counseling for your anger before it negatively affects your daughter.
