All of them.
Can we just confiscate every gun in the hand of civilians?Then there would be zero deaths by gun violence.
But wait a minute....how do we get the guns from criminals and law breakers? I don’t think they will willingly give up their gun by suddenly abiding laws. They are law breakers in the first place because they do not follow law they do not like.
The liberals never explain how they will accomplish the task of getting guns out of the hands of law breakers. So if all guns were made illegal, only the law abiding people would have no guns while criminals still have them.
