"Whatever he thought it was"? Now you're getting into Bill Clinton territory. Please stop dragging this out.
(1) Witt testified that he was walking straight toward Elm St. (2) He ID'd himself as being in the photo showing him and The Cuban sitting on the retaining wall after the kill shot. (3) He testified something along the lines of, "We just sat down" following the kill shot. ALL of this clearly shows what section of the "Grassy Knoll" Witt was referring to. It helps to be familiar with the entire Witt HSCA Testimony.
You just argued that: a.) Witt claimed that he was on the grassy knoll and b.) that the Bronson film shows that Witt was not on the GK. I pointed out that he can easily be seen in the Bronson film standing in front of the Pergola, and that many people consider that the GK to be the grassy area north of Elm. By implication, Witt would have been on the knoll if the more expansive definition was used. Also by implication, the Bronson film is not proof that Witt lied or otherwise misrepresented his position.
Your response was "well,
I define the GK to be...." But it's not about how you define GK, but how Witt would have defined the term. Is it really that hard for you to follow along?
