JOHN - You well know that "vehicles on Elm St" at roughly 12:40 were NOT part of the JFK Motorcade/Parade. When Darnell filmed the BUS and that Cop Car going under the Triple underpass THAT was the Official End of the JFK Motorcade. If you have doubts, just look up the schematic of the JFK motorcade. You said it took "a few minutes" for the JFK Motorcade/Parade to exit Dealey Plaza. If you want to retract Your Claim and the ensuing timelines of Images and Individuals that claim Altered, just do so. STOP trying to manipulate the vehicles that were Officially included/documented as being in the JFK Motorcade/Parade.
When discussing the visual record you need to illustrate and prove your evidence, asking me to find your evidence is incredibly lazy and has a huge impact on any credibility that you had left.
Btw what was the exact timestamp of the Darnell footage I posted?
