Aside from the four rules of safety I can't really think that laws regulating the possession, portage or use of firearms is needed. Last time I checked it was against the law to hurt someone or destroy their property, be that with a gun or bat or your limbs. What else is there that needs to be acted upon. Gun control has absolutely little to do with protecting people. It is ONLY about controlling those people who care about or bother obeying the laws. They do absolutely nothing to control the actions of those few among us willing to harm to others.

As far as I'm concerned if you're mentally unfit enough to not be trusted, or are criminally oriented you shouldn't be out and about among people at all. But them I'm often called an intolerant asshole.
