Guys, I responded to a "man with gun" call standing outside of a bar when I was in my second year of Police work. When I received the next radio update (no, we didn't have computers in our cruisers like ALL do these days), the dispatcher said, the "suspect is saying he wants police to shoot him."
That second update made my heart pound as I was two miles out, and was the closest unit responding. (I had the worst luck doing that job back then.
When I arrived, the suspect started screaming and yelling at me to shoot him. I had my dept. issued Glock 21 .45 out of my holster, but was holding it at my side as I tried to reason with the drunk who was angry over a woman in the bar. I had tunnel vision, my palms were sweating so bad I kept thinking, "don't let your grip slip," and my a** was PUCKERED I was so scared. He raised his .32 caliber piece of junk, and pointed it at me. I shot him twice in the chest, and he died on the scene...
I re-live this very often, and I can see it like it was yesterday. I was placed on paid admin leave for eight days, handed over my gun to the shift Sergeant, and had to go through mandatory counseling which the department paid for.
BELIEVE me, this is NOT something you EVER want to live through. However, had I not acted when I did, I very well may not be here today as his .32 (as junky as it was), was loaded, and ready to go.
My heart pounds as I type this... None the less, my point is you probably won't be in a situation like I was in anytime in your life. However, you could very well be in a situation where someone wants to rob you, beat your brains out of your ears, or whatever. You don't shoot to kill, you shoot to live... You shoot to stop the aggression. I wish he hadn't wheezed, bled like hell, and died in front of me as a crowd gathered. I truly wish he hadn't died! All I wanted was to shoot to stop him, and couldn't help the fact that he died. I pray none of you ever get in a situation where you have to shoot to stop an aggressor. But know that if you do, and they die as a result, you have no control over that.
