Individuals that commit crimes intentionally, take their own rights away knowingly and willingly. Would you rob a bank and think there would be no penalties if and when you are caught?
Criminals know that they give up legal rights and don’t care. I’m sorry if you think not allowing dangerous people to have guns is illogical. I believe that and I’m guessing, but probably most people don’t want psychopaths to own guns.
The remainder of your comments purportedly having something to do with what I think is just amusing.
