Mr. POTTS. No, sir; all I did was just to go down to the jail door and walk with the showup out to the stage, and I stood out on the stage while the showup was conducted. Mr. BALL. How was it conducted? Describe it. Mr. POTTS. Well, there is an anteroom before you get to the showup stage. Now, the witnesses were out front behind this transparent black nylon screen. There's a light set at an angle on the stage where the person on the stage can't see the people out in the audience. They brought them out handcuffed together and this John Thurman Horne went in first--no, that's wrong--Lujan went on first, because he would be No. 4. You see, they're got numbers above the--above them higher up there. Mr. BALL. What is his full name? Mr. POTTS. Daniel Lujan, and then Oswald was No. 3, Knapp No. 2. Mr. BALL. What is Knapp's full name? Mr. POTTS. David Knapp and John Thurman Horne was No. 1. Mr. BALL. And what happened then, after they went out on the stage? Mr. POTTS. Well, Detective Leavelle--now, I don't know who the witness was that they were showing them to--the showup to. Mr. BALL. Did you hear Leavelle? Mr. POTTS. I heard Leavelle question each one of the men. There is a black square on the floor and he tells each one of them to take one step forward and they have a microphone above, and I don't recall exactly what he asked them--It was just to get them to talk and identify themselves. We conduct them different--sometimes we ask them their names and their address and their occupation. Mr. BALL. Did you ask the questions? Mr. POTTS. No, sir. Mr. BALL. Did Leavelle ask the questions? Mr. POTTS. Yes; he was up there. Mr. BALL. And, did he direct his questions to the men on the stage? Mr. POTTS. Yes; to the men on the stage. Mr. BALL. Did you hear them? Mr. POTTS. Yes; I heard them answer. Mr. BALL. Did Oswald speak up or not? Mr. POTTS. Well, he was complaining all during the showup. He had on a T-shirt and the rest of them didn't have on T-shirts, and he was complaining, "Well, everybody's got on a shirt and everything, and I've got a T-shirt on"--he was very belligerent about the showup. He wouldn't cooperate in any way. He was just making all kinds of commotion out there and he was doing more of the talking than anybody. Mr. BALL. What kind of commotion was he making? Mr. POTTS. Well, he was doing a lot of talking about him being in a T-shirt, and "nobody else has got on a T-shirt and I've got on a T-shirt, this is unfair," and all that--just generally talking and after the showup was over, we just accompanied them back from the stage out to the anteroom door and just walked along with them and the elevator--took them on the elevator, and that's all we had to do with the show. Mr. BALL. That's all you had to do with it? Mr. POTTS. Yes. Mr. BALL. What were the appearances of the four men who came out?
