Resolution

I was thinking, earlier today, about Nick Berg's death. As the news of his murder was first circulating, some of my LJ friends were pointing at things in the video, or in the events leading up to his death, that appeared inconsistent with the story presented in the video: that he'd been kidnapped and executed by Muslim terrorists while the videotape was rolling.

And I was wondering: did anything more ever come of that? Was a hypothesis advanced that explained the apparent inconsistencies? Were the concerns of armchair bloggers refuted by mainstream sources or official channels? Does anyone here know?

[Edit: Here's an example of the inconsistencies that were being discussed at the time.]
