What was being discussed in the thread (and implied in the video) was that the old man who fell caught what appears to be a detonator in his hand, and then threw it into the path of a man in a blue jacket (who appears to have been signaled to go towards him), who picked it up what may have been a piece of evidence from where the old man left it. It is referred to as the new Zapruder film as this might indicate real evidence being presented about what actually happened in Boston.

The video is less than a minute and a half and is narrated by someone with an accent, possibly Aussie. Apparently it has not gotten any play in mainstream US media (surprise, surprise) and I am wondering if it is having problems here for some reason.....
