I can't speak to its behavior on iDevices, but regarding the complete video: As far as I can tell all the clips analyzed were from the video footage in the original NYT report[1] of the incident, which is linked in the very first paragraph of this article. Personally, I think this is a rather good example of reporting on something that perhaps entailed a bit of a judgement, but providing ample and well-documented evidence of how they reached that conclusion. If you disagree, you're more that welcome to go to the source material and come to a different conclusion.
