The limo certainly slowed down in the region of Z330. If you follow the white marker in the grass, you can see the marker slow down when SS agent jumps on car. It hangs in the cogs for a long time! Also, I want to see someone catch a car at 8 mph and jump on. You have to be a super athlete! Even Jean Hill in her first interview said the car momentarily halted.
If it didn't halt, it came to a very slow pace to allow the SS agent to leave the perch on the car behind and run up and jump on. Can you dispute that? The film should be called the Zapruder Illusion as you see evidence of cleverly hidden cut and paste lines. If frames are all there, they have been modified to paint a particular picture and obscure identities and support the LNer narrative. In 3 frames, SS agent is even with the policeman on the bike! So he moved 3 ft conservatively in 3 frames. A car speed constant at 8 mph speed and a film speed of 16 fps, we get the SS agent speed of 16 feet/s (11 mph!) Sure!!!!
Again, no idea how advanced editing techniques were in the day but I am sure they were quite remarkable and that they edited the film in such a short time is truly amazing. Again no one wants to comment on frame Z337 and their sloppy editing. So I will present another. They were masters at using the light and cutting film at just the right interface between sunlight and darkness. Besides that, the image from the camera is way more blurry on one side of the cut than the other on Z334. We get better focus in the cogs or generally on the left hand side of the image! I guess I am the only one that can see that. The SS agent in the cogs is not affected by camera jiggle!!
I would like to see someone use photo recognition software and compare the one morgue slab picture of the president in Wikipedia with a regular photo to see if they could actually get a match. I think it is ridiculous to have the President's head missing on the Zapruder Film (front blown off) and then see a picture of him laying on the table with eyes wide open (uhuh) and stating they used an existing wound to do a tracheotomy. Can you imagine the risk of a side tracheotomy with veins and arteries (jugular and otherwise) and associated nerve damage to bore a hole into the windpipe from the side? Give me a break!
How some people can get off on saying that there is a "bone" laying in the spot where the ear is on the photo is incredible. No evidence of an ear shaped bone with scalp folded over in Ida Dox's drawings! Why is everyone avoiding the reality of what you can obviously see below in these frame which compare nice to each other if it was left unedited - I haven't a clue! Ear is present in both photos but one has photoshopping! Even suit jacket/collar ruffle matches!
