Mr. Stern. Can you summarize for us briefly the security arrangements at Love Field?
Mr. Dulles. Could I ask one question about the car before we get to Love Field. There has been testimony here that the back seat, the seat in which the President and Mrs. Kennedy had sat, could be raised or lowered I believe by the President himself, could be raised so he could get a better view of the surrounding people, and then it could be lowered and put in a normal position. Do you know anything about that or how that mechanism worked and who worked it?
Mr. Lawson. No, sir; I am not familiar with his car except for the fact that I know that you can raise or lower the seat. Now whether that is done by him or in the front seat, we do have people that would be competent to tell you that, however.
Mr. Dulles. You don't know whether that seat was raised at this particular time?
Mr. Lawson. No, sir.
Mr. Dulles. As the car went——
Mr. Lawson. I don't believe it would have been starting out.
Mr. Dulles. I was talking about it at the time of the shooting.
Mr. Lawson. No, sir; I have no idea.
Mr. Stern. Could you now just very briefly and generally summarize the security arrangements at Love Field and your participation in them. Were they under your control and supervision?
