Guns don't kill people, bullets do. A gun is as useless as a paper weight with no bullets. Crazy happens, you will never stop people from killing others. When you take away guns in the name of protecting people, you actually take away the protection people already had. That will leave people less safe.

Even if you only ban semi-auto weapons you can kill multiple people. For instance, if you put a side saddle on a single shot shotgun that holds 6 shells on each side you can have 12 shells on the butt stock of the guns. More shells on a belt, if you practice you can be very accurate and fire at a high rate of fire. Its time to live in the real world and realize there are some very bad people out there, taking guns would only allow those people to roam uncontested. Remember the guy in Norway that killed 80+ people? I'm pretty sure if someone there had a gun that could shoot back, that number wouldn't be eighty.

To bad schools don't allow a couple administrators to carry or at least have a hold area for a weapon or two. I would be willing to bet if someone with a gun were close enough there wouldn't be as many children killed.
