All of the above, from a certain point of view...but always a danger to those it's pointed at. The problem isn't so much the guns themselves as the people handling them. Do I use a gun to protect my home and myself? Or do I use it to hold up a liquor store? Do I use it to start an insurgency? Or do I use it to go hunt deer? The choice is always that of the wielder. It's just too bad that so many people feel compelled to use them for destructive purposes...I personally like guns, but I'm just a researcher. The most I do is go down to the shooting range with them.
