Holt and Jacob both describe walking about 50 yards towards the underpass
Simmons states they were about half way between the TSBD and the underpass
All consistent with a location somewhere near the Stemmons sign.
No, the Stemmons sign was about 70 yards from the TSBD entrance, which was still way short of "half way between the TSBD and the underpass".
Try to have your facts straight before you criticise, it would make you appear less buffoonish.
I always have my facts straight. If you weren't so defensive and combative whenever you make unsupported truth claims, it would make
you appear less buffoonish. The people you always claim (without evidence) to be Holt, Jacob, and Simmons aren't even standing by the sign. It just appears that way because of the perspective from Zapruder's position.
