The lack of damage to the windshield in Altgens 6 has already been pretty thoroughly explained. Yourf OP fails completely at that point, and can't be resuscitated by anything Weldon presented.
Another surreal denial that simply ignores contrary evidence.
So never mind that Weldon demonstrated with a huge enlargement of Altgens 6 that the photo shows windshield damage? Never mind that Waldon also demonstrated that some subsequent printed versions of Altgens 6 were altered to conceal the damage? I mean, he proves this for all to see in his 1999 presentation. Did you even bother to watch the video of the presentation?
And what about the windshield damage visible in some of the pre-Z256 frames of the Zapruder film in the MPI large-format version of the film? If you spend a small amount of money and buy the DVD of the MPI version and play it on a large HD flat screen TV, you can see the damage with your own eyes in at least a few of the pre-Z256 frames that Dr. Mantik discusses. We both know your theory of the shooting has no plausible explanation for that damage, which is why you won't admit its existence.
