Mr. Smith. No, sir.
Mr. Liebeler. Are you familiar with the traffic patterns on these three streets here, Commerce, Main, and Elm Streets, as they go down under the triple underpass?
Mr. Smith. Yes, sir.
Mr. Liebeler. The motorcade came down Main Street from the east to the intersection of Main Street and Houston, did it not?
Mr. Smith. Yes; headed west on Main.
Mr. Liebeler. Yes; and it turned right on Houston Street and then turned left on Elm and was headed toward the triple underpass when the assassination occurred. What would have prevented the motorcade from going directly down Main Street under the triple underpass, remembering now that the motorcade wanted to go onto Stemmons Freeway?
Mr. Smith. I don't know, sir.
Mr. Liebeler. Now, could you have gone straight down Main Street and gotten onto Stemmons Freeway down here?
Mr. Smith. Yes, sir.
Mr. Liebeler. Where the three streets go under the triple overpass, there is a concrete barrier between Elm Street and Main Street; is there not?
