Mr. Hill. From the time I got on the back of the Presidential limousine, I didn't really pay any attention to what was going on outside the automobile.
Mr. Specter. Had you noticed the overpass prior to the time you got on the Presidential automobile?
Mr. Hill. Yes; I had scanned it.
Mr. Specter. And do you recollect what, if anything, you observed on the overpass at that time?
Mr. Hill. There were some people there, but I also noticed there was a policeman there.
Mr. Specter. Approximately how many people would you say were there?
Mr. Hill. Very few, I would say—maybe five, six.
Mr. Specter. And how were you able to identify that there was a policeman there?
Mr. Hill. He was wearing the uniform—presumably a policeman.
Mr. Specter. What color uniform was it?
