So you really are equating any traffic on Elm with the presidential parade.
LOL
Of course Mytton is Now forced to "equate any traffic on Elm with the presidential parade". If he takes Any other position, he is then Locked into his original statement that the actual JFK Motorcade exited Dealey Plaza "several minutes" After the Kill Shot. This "Several Minutes" would alter current time lines assigned to assassination films, photos, and the individuals contained on those images. Plus, we then are also into a possible JFK Limo STOP on Elm St. Mytton is trapped in a box of his own making and getting all kinds of flack back stage from the Pioneer JFK "Research" Community that has sat back and simply rubber stamped the WC Hog Wash for 55+ years.
