Mr. Griffin. Were you working on any particular cases that you recall?
Mr. Harrison. No, no; I don't.
Mr. Griffin. Now, during the period that you were there prior to 4 o'clock, did you see anybody on the third floor or elsewhere in the building who you knew was not a police officer or a member of the press or somebody who was up on some sort of official business with the police department, did you recognize anybody that you knew?
Mr. Harrison. No, no.
Mr. Griffin. Did you see Jack Ruby there at anytime prior to 4 o'clock Friday afternoon?
Mr. Harrison. No, sir.
Mr. Griffin. You do recognize Ruby by sight, do you not?
Mr. Harrison. Yes.
Mr. Griffin. Do you know Jack personally?
Mr. Harrison. I knew him as a businessman as well by sight, and I have known him for 12 years, I guess, as a businessman.
