Of course, this would leave all honest citizens at the mercy of criminals. Of course we could take this line of reasoning further. More American children are killed every year in car accidents than by misuse of guns. Thus, we should ban all cars. Furthermore, let us start making homes safer.
Most homes have dangerous items like knives or potentially dangerous chemicals like cleaning fluids.
In schools, we find baseball bats, lacrosse sticks, and footballs. The lists, in fact, is endless. The reason is clear. It is not the inanimate objects which kill, but the willful misuse of these items which lead to injury or death. Other gun control advocates have a very different agenda.
