Many have faced enraged exes...many have died, both sides, glad you survived.

As mentioned prior, somewhere, the military spends a lot of money to train folk to run towards gunfire, rather than away. It is even in manuals/handbooks as to proper reaction in certain scenarios.

And still, a hard instinct to break, the running the other way. That deputy was able to excuse inaction by following old SOP, establish perimeter, call in description, hold position and await reinforcements.

My gripe is he is old. Most of us older folk already can see we are dying sooner rather than later, and nothing really to lose and everything to gain by charging in. Some of us have already been there, seen the elephant as a Civil War soldier called it, and that is no guarantee of nuthin', as several disgraced prior hero soldiers have shown. I have no idea about this guy, but he was old enough to know better. Personally, can say I know what I would do, which is cross myself and ask for success but not my will be done...nothing heroic, but a chance to choose manner of death rather than guess what the short future holds, much of it downright pathetic....a younger guy, with a forever future, maybe wife and kids, I can see hesitating, but not grandpa...
As mentioned also prior, here is an old fart reaction typical....

That deputy will live in hell the rest of his life, and hear those shots and screams for the rest of it, and know he should have done more. He has his punishment, already. Folk should have only pity for him, now.

PS- the above was mentioned because what happened and didn't was cause for a great amount of soul searching, as it likely is for about everybody, after the reflexive reaction is passed.
