There is not a policeman in the world who can respond quicker than an armed victim.
If a policeman is required the victim may end up being DEAD!
And criminals, (get that? As in criminals are criminal because they don't obey the law, that makes them criminal) are not going to worry about gun registration and if it's legal or not. I mean let's face it anti gun nuts are a special kind of stupid and in their case, you can't fix stupid because is "spills" over into everything they do. So, when an intruder is in my home do I wait for the police and die or defend myself and family? The answer is obvious unless you are Feintein!
