require the registration of all "arms" and the registered owner is criminally liable for any illegal use of the weapon.

Make constitutionally protected gun owners fully responsible for the use of those weapons. Strongly encourage gun owners to keep weapons very safely locked away by holding them criminally responsible for any illegal activity tied to those weapons. This includes use by family members, use following theft, illegal use by anyone. You bought it, you are responsible for the outcome. Someone is killed with your weapon, you are charged, you are negligently complicit and wholly responsible.
