Dorner shoot-out

I'm currently following the "developing" situation with ex-LAPD member Christopher Dorner who killed several people before fleeing to the mountains. CNN's "The Situation Room" with Wolf Blitzer (I love that name) is all over this. Apparently Dorner wrote a manifesto which is an instructive read:

Do not deploy airships or gunships. SA-7 Manpads will be waiting. As you know I also own Barrett .50′s so your APC are defunct and futile.

I'm guessing he didn't take his SA-7s or 50-cals with him on his hike around Big Bear. The manifesto shows a lot of signals that he is very far from being in his right mind.

Dorner is reported to be cornered in a cabin in Big Bear, California. He may have access to a TV, he's surrounded by cops and lots of shots have been fired. LAPD are demanding that he give himself up, but he doesn't seem inclined to do so. This ends one of two ways:

1. he exposes himself to a sniper's shot, deliberately or accidentally: game over. At that close range headshots should be relatively easy.
2. LAPD fire tear gas through the windows, he comes staggering out firing wildly, see point 1.

This guy doesn't intend to go to jail. If he does, it's going to be due to a sniper shot hitting him in the torso in a survivable area and immediately incapacitating him. If the cops with AR-15s start firing, they're not going to stop before he's Swiss cheese.

At least Dorner's capture/killing will stop the LAPD shooting random civilians whom they mistake for Dorner. Who gave these guys their access to firearms?

Update: as of 4:20pm Pacific time, the police appear to have started an assault on the cabin by firing tear gas through the windows, as per option 2 above. It sounds like ammunition started cooking off, but Dorner hasn't emerged; it's anyone's guess as to what has happened, but my personal bet is that he took his own life once the gas started to spew out. An outside chance that he got hit by his own ammunition cooking off.
