What is a "licensed owner" per Alaska law? A person is either a prohibited person by law or not a prohibited person by law. A person either commits violent crimes or does not commit violent crimes.

How, exactly, do you propose to prevent those who will commit violent crimes, prohibited status or not, from acquiring weapons?

It's easy to say "do something," but specifics are rare. It usually comes down to platitudes divorced from all extant research and basic logic.
