But what's a "reasonable" restriction. To Teddey the fat, Obama, Feinstein, Brady, Earwax, Hillary, etc. it is absolutely reasonable to restrict all firearms to only their beloved police and their hated military. To me reasonable restrictions are if you can afford it then it's reasonable that you have it. When you have a right with restrictions, then it isn't a right.
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.
