Where did you get Calvary being the one that talked to/sent DPD Officer Smith running down the Elm St Ext?
Storing,
I didn't say that Calvary and/or Smith did that; that's what the person who created the animation, Mark Tyler, shows in it.
I posted the animation not to argue with you about the precise positions of witnesses before, during and after the shooting but to show the positions and speeds of the vehicles in the motorcade so that you can realize that a crucial element of your tinfoil-hat conspiracy theory, i.e., that the bad guys edited out a fairly short but highly incriminating section of the Zapruder film from Z-132 to Z-133, is (pardon the pun) dead wrong.
In fact, as we can see in the animation (which Tyler synchronized with the DPD radio transmissions, photos, films, and known actions of the witnesses), the limo was a whole block (i.e., about 18 seconds) behind the three motorcycles when they started turning onto Elm Street at Z-001.
In retrospect, it's a good thing that he turned his camera off at Z-132, because if he'd kept it running and filmed the incredibly exciting lead car's turning onto Elm Street, traveling towards him on Elm Street, and passing out of his camera's view on Elm Street, he may not have had enough film left to "capture" JFK's and JBC's being wounded by CE-399 around Z-222, JFK's head's going forward and down about 2.25 inches between Z-312 and Z-313, and the explosion of the front-right top and side of JFK's head in Z-313, itself.
