Guns are designed to propel bullets quickly and accurately. This is used for whatever people want to use it for, including sport, murder, and saving lives.
I don't have a gun, in fact I believe that having a gun for self defense may increase your possibilities of getting killed, let me explain it.
Where I come from people are not trying to kill you, they are trying to steal your wallet or something, and if someone points a gun on me, i would prefer to give that person my wallet than to take out a gun.
Its just my opinion and I don't want to take the risk of someone shooting me because I pulled out a gun.
Actually, there's no "you" or "me" explaining it. The math behind the question is complicated and most people instantly fall into the mistake of pretending it is simple.
In retrospect, it perhaps should not have been surprising that increasing the number of civilians with guns would reduce crime rates. The possibility of armed victims reduces the expected benefits and increases the expected costs of criminal activity.
I am not anti-gun or anti-hunting. But "sport" usually means killing things (unless you're talking clay pigeons), and so does saving lives. Injuring at least. They are designed to propel bullets quickly and accurately so that the bullets can strike living things. Shooting cans isn't the intended purpose (although it can be a lot of fun).
