Mr. REVILL. But this is the address I was given. Mr. RANKIN. Now, you say here that you were told that the subject was a member of the Communist Party. Is that right? Mr. REVILL. This might be my interpretation of Mr. Hosty saying a Communist killed the President and we had him in our security files. Mr. RANKIN. You are an expert in this field, aren't you? You are working in the subversive field? Mr. REVILL. Yes, sir; but as far as an expert, I wouldn't say I am an expert. Mr. RANKIN. You know the difference between membership and a person being a Communist, don't you? Mr. REVILL. Yes, sir. Mr. RANKIN. And you know it is a very real difference? Mr. REVILL. Yes, sir; there is a difference. Mr. RANKIN. Do you know which Mr. Hosty told you? Mr. REVILL. He did not say that he was a member. This was my connotation of what he said that a Communist, that "We had him in our security files." Mr. DULLES. Could I ask a question? Where did you get this address that you put on of 605 Elsbeth Street, do you recall? Mr. REVILL. Yes, sir; from Detective E. B. Carroll or Detective Taylor. Mr. DULLES. Are they subordinates? Mr. REVILL. No; they are detectives assigned to the special service bureau. One of them works the narcotics squad and one of them is assigned to the vice unit. Mr. DULLES. You never ascertained where they got it? Mr. REVILL. No, sir; this might be the address that they got from Oswald, I do not know. I never even thought about it until you brought up the point that this is not the address. Mr. DULLES. Can you find out where they got this address? Mr. REVILL. Yes, sir; I can. Mr. DULLES. I think that would be useful. I would like to know that. I would like to know where they got this address also. Mr. REVILL. It would have been the same day because this was made within an hour---- Mr. RANKIN. You didn't put down on this statement anything about what you said, did you? Mr. REVILL. No, sir; I did not. Mr. RANKIN. Why didn't you? Mr. REVILL. All I was doing was reporting what Mr. Hosty said to me. Mr. RANKIN. Is that the way you make all your reports just one side? Mr. REVILL. Yes, sir; yes, sir. Mr. RANKIN. You never say what you said? Mr. REVILL. No, sir; I do not put our opinions or our interpretation in the report. Mr. RANKIN. You don't even say what you asked? Mr. REVILL. No, sir. Mr. RANKIN. You just put the answer down? Mr. REVILL. Put what was given to me; yes, sir. Mr. RANKIN. And that is the way all the police department reports are made? Mr. REVILL. No, sir; I don't know whether this is the way they are all made. This is the way we do it in our unit. Mr. RANKIN. After you made this report, do you know what happened to it? Mr. REVILL. I gave it to the captain, my captain, Captain Gannaway. Mr. RANKIN. Do you know whether it was given to the Commission when the police reports were furnished to the Commission? Mr. REVILL. This I do not know, sir.
