Skeexix:  I like GBA and support his comments.   I have owned guns for over 50 years as well and NONE of them have killed anyone.  I have NOT had to kill anyone, YET.....One month ago in the middle of the afternoon I was sitting on my sofa drinking a glass of ice tea, taking a break from yard work.  I usually have my front door open for fresh air.  All of the sudden a kick on my screen door, a guy I did not know standing there.  He states, I am here to buy some METH. I said, you got the wrong house TWEEKER.   I had my 45 cal. right there.  I grabbed my weapon, told the guy  DO NOT come in, if you come in I will shoot you.  I walked to the screen door with my weapon pointed at his chest.  The TWEEKER looked at the weapon and IMMEDIATELY took off.  Now, my GUN did NOT have a MIND of its OWN and kill him.
