Let me start by saying that I enjoy THIS forum, mostly because I have come to respect Rob, Mike J, and Mike B. I like their collective common sense attitude toward keeping your butt wired to your head, and all limbs working properly. Another big reason I like it, is that I don't see a bunch of tactical teddy wannabe high speed low drag operators who wear their 5:11 gear to their cubicles at the insurance office, and are prepared to do battle on the way to the coffee machine with their tacticool folder until they can get to their hidden Krink in their tactical briefcase.
Having been in two real life deadly force encounters while I was still a police officer...I can tell you that you WILL want to KNOW you were right and HAD to shoot. I am not talking about being able to make it SOUND like shooting was reasonable, and the only option. I am talking about KNOWING in your mind that it was truly the ONLY way you or your family would survive.
There are several other times in my LE career, and one time in my new career as retired full time dad, where I COULD have used deadly force. It would have been, according to the letter of the law here in AZ, totally justified. However, I didn't HAVE to use deadly force...and boy howdy, I thank God Allmighty I didn't take a life in those situations. The situation was resolved by the subject KNOWING that I was WILLING AND READY to end the encounter with gunfire if neccessary, and they made the choice to live and allow me to go home once again to my family with no blood on my hands.
A person who shoots someone, even if they don't KILL them, if there is another way that allows you to accomplish your own survival without having to shoot someone, is just crazy. My gun is my last resort. If all I had was a hammer, then all my home repairs would start to look like a nail. The only tool in my toolbox is not my pistol.
I don't want to get preachy. I will go to ANY length I need to in protecting my family, and one of those lengths is to use restraint when I can.
Be safe all.
