Mr. PIERCE. That's an emergency. In other words, that is, we have code 1, which is normal driving; we have code 2, and a code 3. In other words, code 3 is your top--proceed with haste and caution. The transmission followed that at 12:44, "Attention all squads, the suspect in the shooting at Elm and Houston is reported to be an unknown white male," and gives the description here--would also be an indication to the squads, and reading this--and I assume that this is the way it came out--a man would have to draw his own judgment, because it hasn't told you yet that the President has been shot, but I would think that any normal police officer would assume that there had been something pertaining to that, probably, and it would be normal procedure for him working in the district he is working in to pull into a closer area to the downtown area, and this district 109, which is, I believe you stated, that as being at Eighth and Lancaster--it doesn't show here on your map, but you have no viaduct--that's about the only place you can cross that river, unless you want to wade. Mr. ELY. Could you mark on the exhibit with your red pencil where that viaduct would be? Mr. PIERCE. Well, you see, Cadiz Street over here in the downtown area--it also crosses this river and comes on out--may or may not be nearly correct--it isn't too far from wrong--I don't think so--there is two viaducts. Mr. ELY. The red mark you have just drawn is what? Mr. PIERCE. The red mark is one viaduct that crosses that river and the area where he was at that time, I will just have to use this--Lancaster Street comes in something like that--it isn't marked on here. Mr. ELY. All right. Mr. PIERCE. But, he wouldn't be too far from that Cadiz Street viaduct. Anyway, they come over that Cadiz Street viaduct, and also you have quite a few apartment houses along there on Lancaster and Marsalis. In other words, there is a large number of people that live over in there. That seemed to me like he was probably using pretty good judgment in getting in that particular area because he would have a chance there to assist from the downtown area there. Mr. ELY. This transmission to which you referred, the one appearing at 12:43 p.m. on Sawyer Deposition Exhibit B, purports to be directed only to all squads in the downtown area? Mr. PIERCE. That's right. Mr. ELY. But you think it would be normal even for those squads not located in the downtown area to react? Mr. PIERCE. I would have to call on my experience in the Dallas Police Department. Under normal police procedure we request that the squads stay in their district, but under any emergency situation we do not require that they stay in their district. Mr. ELY. So, you would characterize this as a normal course of behavior? Mr. PIERCE. It looks like a normal procedure to me. Mr. ELY. All right. Do you think of anything else that you would want to mention in connection with this, or do you think that just about covers it?
