Mr. Lawson. Detectives, 40; department of public safety uniformed, 40; rangers, 5; plainclothes, 16; Dallas County Sheriff Department, 14; fire department, 26; the White House detail agents, 20; agents from the Vice President's detail, 4; agents from the Dallas office, 4.

Mr. Stern. So there were 28 Secret Service agents involved?

Mr. Lawson. Yes, sir.

Mr. Stern. At the various locations. Do you know whether the Dallas police who were used were full-time policemen or were auxiliary policemen?

Mr. Lawson. I do not know.

Mr. Dulles. Do you happen to know the circumstances under which there were some certain changes made as to the location of the motorcycle escort that went close to the President's car?

Mr. Lawson. I know that their position varied, depending on the crowds.

Mr. Dulles. No, I mean apart from that, apart from the crowd situation do you recall that any orders were given by or on behalf of the President with regard to the location of those motorcycles that were particularly attached to his car?

Mr. Lawson. Not specifically at this instance orders from him. Just what I know to be the case from other advances, that unless it is necessary, it was my understanding that he did not like a lot of motorcycles surrounding the car. That is why we had four just back of the President's car, so that they could come up and intercept anyone running out from the sides easily, or we could call the other motorcycles back to him if we had to.

But if there are a lot of motorcycles around the President's car, I know for a fact that he can't hear the people that are with him in the car talking back and forth, and there were other considerations I believe why he did not want them completely surrounding his car.
