Something I've been munching over as I've read this thread, and thought awhile about is the importance of getting a long arm into play.
I've read about some LE deaths in shootouts and keep coming back to the thought of
"If that poor guy could have gotten his patrol carbine or riot gun working, he might have came out alive."
Therefore, I suppose situational awareness is critical in that if you can anticipate the situation prior to shots being fired, perhaps you can achieve the critical edge and bring your long arm into play.
"Growing up as both a Southern and the son of a child of the '50s, I was imprinted with several things that have long stuck with me. The F-86 Saber Jet was the finest fighter ever flown, the National League is always superior, and Leslie Coffelt
was the finest revovler shooter since Mr. Ed."
