The main difference between what happened in China and what happened in Newtown is that not a single person was killed in the China incident. Not a single person was killed. Your always going to have criminals and mentally unstable people, but if they don't have the tools then you don't get the outcomes that happened in Newtown. Katie, the example you cited basically disproved your entire position.

I'm so sick of people hiding behind a 200 year old document as their rationale for why they get to own deadly assault rifles. You had nothing to do with writing it, have never been educated in constitutional interpretation and have done nothing to support it. You were just lucky enough to be born here and thats arbitrary at best.

I find it interesting that the same people who scream for their gun rights are the same people who want to restrict everyone else's rights when it comes to other personal freedoms (religion, marital rights, adoption, abortion, drugs). You can't have it both ways.
