I've carefully reviewed the video numerous times. In slow motion you can clearly see in frames 183-187 that his heads moves back and to the left, back and to the left. Obviously, there was another shooter in the grassy knoll.

I was a kid but I was there and heard more than 1 shot....

it was Keith Hernandez

Pretty sure I saw a magic luegge in Reggie's hair.

That is Speed Wax, muh boy, Speed Wax!!!

Go Speed go!

KEITH: Well lookit, the way I remember it [back to the grainy 8mm film parody] I was
walking up the ramp. I was upset about the game. That's when you called me pretty
boy. It ticked me off. I started to turn around to say something and as I turned
around I saw Roger McDowell behind the bushes over by that gravely road. …
Anyway he was talking to someone and they were talking to you. I tried to scream
out but it was too late. It was already on its way.
JERRY: I told you!
NEWMAN: Wow, it was McDowell.
JERRY: But why? Why McDowell?
KRAMER: Well, maybe because we were sitting in the right field stands cursing at him
in the bullpen all game.

OK so now all you guys got is making fun of Reggies hai and calling the video a fake? Ya'll are getting weak!

No - I remember the video of Speed Racer as a kid - its real
