Guns are for Killing. And sometimes it is necessary. A Rabid Dog (dingo), dangerous viper, mortally wounded deer. There are plenty of instances where killing is not only necessary, but humane.
Bows and Arrows are for killing. Much more sporting than a gun, but that is their purpose as well.
Knives are for killing. And cutting, but the cutting comes after the killing.
Many things in life can be said to have only one use, when in fact if that were really the case, they would long ago have been relegated to antiquity (Seen any Maces lately?).
I dont own a Gun. Never have. But that is my personal decision. I would not force my decision on others just because I dont own one. That is totalitarianism.
YOur statement and Phoenixboi's go hand in hand. Yes, Guns make it easier to kill, but Killers are going to kill regardless of the availabilty of guns.
Banning Guns does not reduce crime. Criminals are not made by the weapons they own.
