I think there are people with BC’s that should not be allowed anywhere near a firearm. (Or elected office for that matter)
You are half right for sure. Unless a citizen has by rule of law lost their right to own firearms, then they have the right to buy or own them.
Citizens are born with Constitutional rights, have no burden of proof, the onus should be on the government to prove that they have lost their legal right, to own and use guns.
