Do you really believe
regulation is good, as it keeps honest people honest
Behind that statement is the idea that otherwise the firearm itself can somehow change someone from law abiding to not law abiding, and that laws/regulation staves off the evil inherent in firearms.
Dishonest people/criminals will do as they please regardless of the law, as you acknowledge, the law only burdens those who follow it. The law abiding do not need a law saying they can't own this or that in the hope that it would prevent them from killing people...because they already follow the law that says...Don't Kill People...
