Mr. Kellerman. The purpose of that pilot car is to clear the roadway and instruct the officers along the route that the President is in motion and coming in back of them. Next you will find a small group of motorcycles.
Mr. Specter. Do you know how many motorcycles there were in Dallas on that day?
Mr. Kellerman. No; I don't.
Mr. Specter. Will you tell us what the custom is with respect to motorcycles?
Mr. Kellerman. Yes, sir; those motorcycles that would be in back of that police car were to assist any officers along the way in any disturbance that they would run into before we got to that point, or secondly, in the event that we needed them back on our car they could be called, utilized.
Mr. Specter. What is the next car in line?
Mr. Kellerman. The next car is the lead car. That car on that day was driven by Chief Curry of the Dallas Police Department.
His occupants in that car was Special Agent Winston Lawson, who was carrying a portable radio with him. Also in this car was Special Agent in Charge Verne Sorrels, in charge of our Dallas office. The other occupant, I believe, was a deputy sheriff.
Mr. Specter. Was it Sheriff Decker, perhaps, of Dallas County?
Mr. Kellerman. The name doesn't reach me, sir; I am sorry.
