It doesn't matter what the intended purpose is. Do we not have a right to protect ourselves? The police can't protect us in time so we need to do it ourselves and a gun is the best way to do it. If guns were to magically disappear then people would be carrying around swords again. The fact of the matter is that the human race is inherently violent and some will always kill others. Why take guns away from those who do not normally kill others and leave them in the hands of those who do? The number of guns which have killed people are far fewer than the number of guns which haven't killed anyone.
