Yes, soon after--very soon after--the initial request went out by LE to get the video from the media (unusual in itself, ad LE knows they have to sup. that kind of thing)...LE stated through a spokesman (not in an official document) that witnesses had said one thing to them, another to reporters.Was that the reason given by LE?
That might not be the *only* reason they wanted the vids. But, IMO, given the 'dotting i's, crossing t's' statement that was given at the same time, they wanted the vids to see which potential witnesses had given contradictory statements.
