Keyvan, what you are basing your "debate" on is an absurdly ridiculous video, not evidence. You maintain that Zapruder's camera was catching reflections of a County Records Building shooter through the entire length of the film, even when that camera was pointed AWAY from the CRB. We are all aware of the rush of witnesses to the hill, when it happened, and why it happened; yet you insist on maintaining the absurd premise from the video that David properly labeled as "junk".
The person who posted that video has the comments disabled for a good reason; his assertions are indefensible. He was smart to disable the comments, but you decide to carry that rubbish into this forum for debate?
