As reported, a criminal armed with a box cutter went to the back door of an Aurora, CO home during the early morning hours and knocked. When a resident opened the door, the criminal attacked the man, and after a brief scuffle, ran into the living room. There, there criminal found a guest sleeping in the living room, and began to attack that guest. The home owner returned to his bedroom, grabbed his self defense pistol, and fatally shot the criminal, saving himself and his house guest.
This is yet another one of the many examples of citizens defending themselves with a firearm. The fact is that, Americans defend themselves with guns every 13 seconds, saving countless lives each year. While I certainly hope that I never suffer a home invasion such as this home owner suffered, I fully intend to be prepared should a criminal break into my home to cause harm. I see such preparedness as part of being a responsible adult, and member of society in general.
