Mr. Liebeler. So you were pretty sure fairly quickly that the shots had come from the Texas School Book Depository?
Mr. Barnett. Yes, sir.
Mr. Liebeler. There was no notion in your mind that they could have come from these railroad tracks down here around the triple underpass?
Mr. Barnett. To me, it is impossible.
Mr. Liebeler. From the sound of the shots?
Mr. Barnett. The sounds were high, and if it was down here, it wouldn't echo. It would be a low sound. For a shot to echo, it has to be high up.
Mr. Liebeler. You mean to hang?
Mr. Barnett. To hang like that.
Mr. Liebeler. Now there were altogether three policemen assigned to the corner of Elm and Houston; is that right?
Mr. Barnett. Yes, sir.
