Dan, that's interesting because it's not the same show I saw, but it looks like a couple of shots from there were used in that clip. Or maybe someone else did a very similar show, I'm not sure.
I don't know how much stock to put in these Discovery shows anyway. There are some excellent documentaries on there, but it seems to me that some of the newer shows they do are sensationalistic, and the outcome is predetermined.
Anyway, I'm not arguing one way or another what happened that day, because I claim to be sure about it.
One more point, though... It seems to me to be almost immaterial whether he was actually hit by Oswald, which I think he probably was. If there were other gunmen that day, that's what really matters.
