Yup! That'll do it. Prevent all that violence.
Do these morons think that will stop anyone from reloading? Ban mag capacity to 10 rounds and they'll just carry more.
But wait, there's more. Since these shooters are committing a criminal act anyway, what makes the idiots that want the ban think that anyone like this really gives a crap about their laws? They'll find "hi-cap" mags somewhere. It's not like they're scarce.
