Where to start?
If he went out there to stage an incident he probably could have gotten away with it pretty easily so long as he stuck to his story. I can't see a department investigating their own on something like this.
I agree, though staging something like that would have carried enormous risks and it's probably why it failed so horribly.
Where he would have had problems was the back up call. He had to have known where he was going with this before that request if this scenario is that he fabricated it all.
I'm not so sure about that. Assuming the Lt was in fact staging an encounter, we don't know how far into it he was when he first radioed in. Had he already fired the first shot and was still just trying to make it look like he was assaulted? Or, had he made up his mind that he was just going to end it all? To be honest, I haven't tried to process that part yet, myself.
Because once back up arrived and he wasn't dead but only hurt and it was his gun used, but he still has the gun or the gun found nearby with no other prints and backup finds no suspects things are not adding up quick for him.
That is part of the reason that I believe his fatal shot may not have been intentional. I still think there is a chance that he intended for it to look like a glancing shot at an odd angle and he missed his vest. Some of this will come more into focus once we know more about the fatal bullet's exact trajectory.
So once he accepted backup I think he had a pretty good idea he was not going to be around to control any investigation.
I am somewhat inclined to agree with that though I can still imagine it playing out the way the Lt might have wanted it. He
could have intended to survive both shots and have backup arrive, find him down and then take that opportunity to say "they went that way!" That would totally (at least temporarily) take the focus off of his own weapon and such.
His death I think led to the investigation turning to the suspects easier than had he survived once back up arrived the request. Hopefully I understood your post...
You seem to understand it pretty well. As for the investigation, I think anytime a cop calls for backup, the "us verses them" template is almost automatic. Cops are not trained to consider that a downed officer may have just faked an encounter for publicity, for some kind of recognition or to hide a suicide.
