The majority of firearms are designed for one thing only: to kill human beings. It's true that a few guns are specifically designed for hunting: shotguns, for example, Also big game guns such as the 425 Westley Richards Elephant gun. However, the amount of firearms used for hunting would hardly represent more an a few percentage points of those actually manufactured.
It's all very well to say that it is the mentality of the people involved with guns which causes the problem but take away the guns, what have they got left? Well, clubs, axes, knives et cetera. How many mentally disturbed people who wanted to kill as many other people as they could, would run into a school or univeristy campus with only a kitchen knife in their hands?
The point is, if there were no guns, and no artilliery, tanks or warplanes we'd be back to bows and arrows before you could say "Oops! I'm outa bullets."
Take a leaf from places like the UK where most people don't own a gun. America has more people killed with guns in a week than the UK in a year. That has to tell you something....
