Mr. Hill. I think it was blue of some shade.
Mr. Specter. Did you identify it at that time as being of the identical color which other Dallas policemen were wearing whom you had observed in the area?

Mr. Hill. In time or——
Mr. Specter. Time and distance.
Mr. Hill. Distance, I have no idea.
Mr. Specter. How about time?
