Took me a few minutes to piece this together; The wording in the video is hard to follow. The floating tree is in the footage where the driver turns to point at JFK. Though this is claimed to be doctored to provide plausible deniability for the driver, as to it being poorly altered, with a visible bullet, and a floating tree.

I just stumbled across this and posted it to see what people here thought. That's what forums are for. Not everyone is a shill.
