During the JFK assassination, who was in the cars in directly in front and behind of JFK?
Here's what the Warren Commission report said about this:
The order of vehicles in the Dallas motorcade was as follows:
Motorcycles.--Dallas police motorcycles preceded the pilot car.
The pilot car.--Manned by officers of the Dallas Police Department, this automobile preceded the main party by approximately quarter of a mile. Its function was to alert police along the route that the motorcade was approaching and to check for signs of trouble.
Motorcycles.--Next came four to six motorcycle policemen whose main purpose was to keep the crowd back.
The lead car.--Described as a "rolling command car," this was an unmarked Dallas police car, driven by Chief of Police Curry and occupied by Secret Service Agents Sorrels and Lawson and by Dallas County Sheriff J. E. Decker. The occupants scanned the crowd and the buildings along the route. Their main function was to spot trouble in advance and to direct any necessary steps to meet the trouble. Following normal practice, the lead automobile stayed proximately four to five car lengths ahead of the President's limousine.
The Presidential limousine.--The President's automobile was specially designed 1961 Lincoln convertible with two collapsible jump seats between the front and rear seats. (See Commission Exhibit No. 346, p. 44.) It was outfitted with a clear plastic bubbletop which was neither bulletproof nor bullet resistant. Because the skies had cleared in Dallas, Lawson directed that the top not be used for the day's activities. He acted on instructions he had received.
