That is irrelevant to the issue that gun bans are meant to tackle.
Gun bans do not care about who pulls the trigger. They are not directed at legal gun owners.
Gun bans are meant to REDUCE THE NUMBER OF LEGAL GUNS IN CIRCULATION.
Quite simply, a citizen, whether they be criminal or not, should not have an opportunity or have reduced opportunities to go purchase a weapon legally.
All illegal guns start off as legal guns, so reducing the number of legal guns to reduce the potential of them being used for illegal purposes, is justified via a gun ban.
This is why registrations are also necessary.
Holy shit. Are you daft?
I already said, both supply streams are separated, and therefore both controls are needed.
There is no conflation here.
