Mr. WALKER. Well, Officer Tippit was an exceptional officer. He made good arrests. It was known around the station that he was exceptionally good with investigative work and just general police work. He was above normal. Mr. BELIN. Why do you think he stopped this man? Mr. WALKER. I believe that the description given on the radio, that he probably stopped just to check him out as a general procedure, as we do. Mr. BELIN. Well, if he stopped him for that reason, this man, he would have stopped him because the man was a suspect for perhaps the assassination, why wouldn't he have had his gun out when he stopped him? Mr. WALKER. Well, there are a lot of people of that description, and it is just not police practice to pull your gun on a person because he fits the description of someone, unless you are positive almost that it is the suspect. You just don't do it. Mr. BELIN. Let me ask you, did you have anything to do on November 22, or anything more to do on November 22, with either the Tippit shooting or investigation or apprehension of Oswald or the assassination of the President's investigation? Mr. WALKER. No. I stayed down in Captain Westbrook's office for a while until I got off. Mr. BELIN. How about November 23, did you have anything to do that day? Mr. WALKER. That would have been Saturday. Mr. BELIN. Or did you work on Saturday? Mr. WALKER. Yes, I worked on Saturday. I didn't follow up on any investigation of any kind. Mr. BELIN. Were you going back to accident investigation? Mr. WALKER. Yes, I went back to the accident investigation. Mr. BELIN. You didn't have anything to do with anything connected with the assassination after November 22? Mr. WALKER. No. Mr. BELIN. Is there anything that we haven't covered here that you can think of at this time, Officer Walker? Mr. WALKER. Not that I can think of. It's been a long time, and I just don't recall. I think there was more conversation with Oswald, but I can't recall all of it. I just remember what I considered the high points of it. Mr. BELIN. Did he ever ask for a lawyer in your presence? Mr. WALKER. I don't recall. I think he said--I know he was repeating, "I know my rights." I don't recall him actually asking for a lawyer. Mr. BELIN. Did he say where he got the gun? Mr. WALKER. No, he didn't say where he got the gun. Mr. BELIN. Did he admit that it was his gun? Mr. WALKER. Never did ask him actually whether it was his gun. He said he knew he was carrying a gun and he wasn't supposed to, so I assumed it was his gun. Mr. BELIN. Well, we certainly appreciate your taking the time to come down here to testify before us, and we want to thank you very much for your cooperation. Mr. WALKER. Okay. I know you've got a problem here.
