I guess we'll just have to execute em then.
Simply banning guns won't help. Things (or at least relative parts of them to a specific problem) like corruption, laziness, low manpower, education, awareness, poverty, donuts, etc. should all be looked at cuz they all add up for a conclusion.
Indeed, simply banning guns does not help.
and there is not a lot of inventing a law that cannot be effectively enforced.
If guns were outlawed then only outlaws would have guns.
Criminals do not obey existing gun control laws so adding more won't make a difference to the criminal element but instead will only hinder those who already abide by the laws.
