Kiddo comparing guns and poison is like comparing apples and oranges.

One you use to spray bullets into anything that gets in your path, the other you need to feed the victim somehow. Imagine shooters walking with poison instead of guns. Not very scary or effective way of killing people is it?

Guns you can buy at walmart while poison you can buy animal poison but not lethal human grade poison at any stores.

If you wanted to deter burglars why don't you buy a tranquilizer gun instead of guns that can actually kill?

The point is gun kills and it's not a good idea to make it available so easily. As for people who already have guns so be it, maybe some legislations can be thought of, but at least someone who goes psycho from now on can't go to a store to pick up guns and kill people just because he's a psycho, if it's not easy to get hold of a gun.

Let's not get into the definition of assault rifles and guns. In general a gun is anything that shoots bullets with the potential to kill.
