From limited info that I have, it sounds like he knew what was in store for him. A shootout, and subsequent death. (guess what, that is what happens, and he wasn't stupid). If he wanted to live, he'd have had to drive straight south and cross the border. Probably, wouldn't have been tough
He was a murderer and cop-killer, and got what was coming. The police saying they didn't mean to light the cabin on fire is kind of irrelevant, but they may get into some trouble for that (basically execution). Bullets would have worked just as well, and maybe been easier to justify.
Sadly, this event will end up in the courts, being discussed for long periods of time, and lawyers making millions (most of it from taxpayers). In China, they take the bad guys out back and shoot 'em. Case closed. (Really, at least in smaller cities)
