Illusion? Missing windows not visible but there?

[Guest Eugene B. Connolly]

Regarding the apparent changes to the window openings

in the Zapruder film: Has it occurred to anyone

that the possible reason there are no openings visible

may be due to the fact that someone or something is standing

behind these openings and thus blocking the holes

and preventing the light from shining through and

therfore giving the impression

that there are no openings there? What is the height of the

bottom most window from ground level?

Also can anyone provide a picture of the area behind the wall/picket fence?

I cannot find a good picture of this area anywhere on the net.
