The incredible burden on the system. If you are doing arms control you are way past counterinsurgency. If not enforcing,prosecuting and correcting the people who had a legitimate right to protect them and theirs.

Law should promote good behavior and deter undesirable behavior. So rightfully possessing a firearm (or jedi light saber) for self defense where people smash one another like I kill houseflies.

Locks keep honest people out.... guns embolden civilians in their environment.

I wish the world could be violence free and dogs and alligators could lie down in the swamps together but that just ain't the way it is and probably wouldn't be much fun either.
