JJ&E, all in one?
No. Protecting the innocent third person he may run into after showing that he has little or no regard for human life by having just killed someone else and is fleeing into a public place, still armed, that contains lots of innocents and hostages for the taking, that hardly qualifies as JJ&E. If an armed suspect were running into a shopping mall or a day care, I may feel I need to shoot him. If his back is whats available, so be it.
I could argue, honestly, that Coop de Ville took too many chances ordering this guy to drop the gun. How many times should we be expected to order someone to drop a gun? Is his non compliance his way of buying time or building courage to draw his weapon? My uniform is the first symbol of authority, the marked car etc. Next comes my verbal order to comply, I have an armed subject, who is capable of using deadly force against me, or my partner or anyone else, in less than two seconds, who is refusing to obey my lawful orders. I have had many, many confrontations with armed suspects and citizens alike, the good guys obey your orders, the bad guys, bolt and run, or comply.
Techbrute, I'm honestly curious, why does that seem strange or bothersome to you?
Honestly, Coop, I was just using that as an example, many bad guys have gotten away from me in 20 years of doing this, given the situation you had, you did everything right, I would not have shot him either, until I saw the first hint of him reaching for the gun, but, I wouldn't fault an Officer, or citizen for feeling justifiably in fear of their lives when there is an armed guy, within touching distance, that refuses to comply. You chase him, at as safe a dsitance as you can, until you can get help there, or, you lose sight of him. The fact that he did not pitch the gun is actually more bothersome to me than anything, and what you took for him holding the gun while he ran, may very well have been him trying to drag it out of his baggy pants and the front sight was caught on one of the three pairs of pants he was wearing under his street clothes (if your bad guys are anything like ours, they are big believers in the "layering" method)
