IMO the logic that guns dont kill people but people kill people is just crazy (Would you say the same about landmines for example?)
Guns are DESIGNED to kill, that is their sole purpose (unlike a car, baseball bat, or whatever).

The Virginia Tech massacre (32 kills) would not have happened if it where not so easy to buy a gun.
What added security does a gun bring anyway? If everyone owns one doesnt that cancel out its effect?
Criminals will always have a bigger gun than you and in what kind of neighborhoods do you all live if you sleep with a gun under your pillow? (Time to move?)
