Insane people can’t have guns. People previously convicted of a violent crime where there was a weapon as part of the crime may not have guns.
That sort of thing.
Even we disagree on what's "reasonable" And if we disagree on this forum, then obviously there is a wide range of what different people consider "reasonable." For example, I think if a person is incarcerated in either a mental institution or a jail, then no guns. Otherwise I say OK. Take criminals for example. If they're a danger to society what are they doing out of jail, and if they're not a danger to society, then they should be able to defend themselves legally the same as anyone else. Also there is the practical side of it that anyone intent on committing murder or assault with a firearm is obviously not going to pay any attention to a gun control law.
"Reasonable restrictions" only affect the law abiding.
Oh yes they can...I hear ya. The joke of course is that “reasonable restrictions” weren’t intended to prevent the criminally insane or convicted felons from getting guns. Such restrictions have been proven ineffective in preventing crime. They serve only to control the law-abiding (Sheeple).
