Before I say anything else, let me make this perfectly clear - this is not a "all gun owners are bad" blog. Nothing in this world is all black or all white.
I believe that ownership of firearms comes with a remarkable responsibility to the society at large. Since this is a weapon which, depending on it's size and scope, can kill many people very quickly and at varying distances, the individuals who carry such firearms are held to a high standard.
The right to carry a gun does not supercede the right to live. Those in our society who have had placed on their shoulders the responsibility to protect ie., police and the military, have been trained on when, where and how such decisions are made when forced to take a life, and even then, the weight of that responsibility has been painful for those who have had to make that decision.
