Mr. Hardin. We were en route to the funeral home from veterans hospital, and we were on the Stemmons Freeway, about a quarter of a mile southwest of Industrial Boulevard, and we received a call that—at 11:21 over the police radio on signal 19, which is a shooting in the basement of the city hall.
Mr. Hubert. Did you have radio equipment in your car?
Mr. Hardin. Yes, sir; we do. It is police radio equipment. Hooked up directly with the police dispatcher. Just regular police equipment.
Mr. Hubert. Is it 2-way?
Mr. Hardin. Yes; 3-way.
Mr. Hubert. Three-way?
Mr. Hardin. Yes, sir.
Mr. Hubert. What is the third way?
Mr. Hardin. We can talk to the squads and they can talk back to us and we can talk to the dispatcher and he can talk, and we can talk to the squad and the dispatcher.
Mr. Hubert. I see. It is customary for you to have that radio machine open and operating when you are traveling?
