Perhaps you can counter argue that we just need more anti-violence laws? This way, we cover all violence and not just gun-violence. How about we make laws against crime in general? Maybe that might do the trick. While she is at it, we need more narcotics laws, since illegalizing all that seems to work out so well for us and brought about super cool drug cartels with massive resources. The cool thing is that if we illegalize all weapons, we can finally get some organized weapons cartels and then we can all buy machine guns, explosives and wmd's on street corners via neighborhood dealers. I mean, it is actually quite a bit of effort to get fully automatic weapons and high grade explosives, but with Cartels in charge of distribution, it would be way easier.
