Do you think the video is edited or where was the body guard that you think shot him?
I was thinking more of the situation where some people might be confused with the Zapruder recording, that it could be on videotape instead of film, which is why I didn't try to cover all the corner cases.
The first consumer video camera (camera that recorded to tape rather than film) wasn't until the BetaMovie in 1983 with VHS coming months later. Heck, _home_ video recorders were still 15-20 years off at the time.

Obviously "video" existed then in the sense that there was television -- but consumer video cameras didn't appear until around 1979 or 1980.
