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.
