I don't disagree.
Travel in packs seems a good start. I think it saved the first officer struck and whomever else would have faced him after.
The officers who did the shooting seriously wounded a bystander, but in that kind of cement and steel box only hitting one other person is damn near a miracle.
To me options have a lot to do with distance/time and terrain and some to do with tools available.
I doubt the first officer noticed in time to mount much of a defense. The second officer was wounded. The two others saw to the asshole with the ax. The fact the shooters were not the ones the assault was initiated on gave them a moment, and as far as I am concerned they spent it well.
Barring that seeing it coming and acting on that information BEFORE injury confirms intent? Maneuver WHILE assessing instead of waiting to be certain that you need to? I play the whole consistent vs inconsistent thing when evaluating, like my post about the highway shooting, but that is only a way and not THE WAY.
Also, if any one reading this hasn't done so already; resolve to be brutal enough, soon enough.
Keep fighting. Keep trying to solve the problem until you can't anymore.
