The question surrounding the speed of the JFK Limo is also tied into that same Limo: (1) Not being filmed turning onto Elm St and (2) Suddenly Popping into the Z film already traveling down Elm St. Both Zapruder and Sitzman said they could see the Limo traveling down Houston St and turning onto Elm St from their Elevated position standing atop the Zapurder Perch. The Current Z Film is a Sham.
