I believe that Hosty’s interview with Ruth Payne and Marina Oswald shortly before the assassination revealed to Hosty that LHO was living in the Oak Cliff area. But I don’t think that even Ruth or Marina had the address at that point in time (only a phone number). And if I remember correctly they didn’t give Hosty the phone number at that time. I think you are probably correct that no one in the government knew where he lived during the week. In fact, perhaps LHO may have been the only person who knew. Because even the landlord knew him under a different name. Apparently they didn’t check his identification.
Charles, thanks, yes that's my understanding. Hosty said that if Paine/Marina had given him that phone number he could have looked it up and found the address.
Here is Hosty (WC testimony) on the first interview with Ruth (pre-assassination):
Mr. HOSTY. Yes; that is my recollection that we looked it [where Oswald was working] up in her telephone book to show it at 411 Elm Street, Dallas, Tex.
She told me at this time that she did not know where he was living, but she thought she could find out and she would let me know."
In his book, he said he interviewed Ruth after the assassination and she said: "You know, Mr. Hosty, when you first visited on the first of November you were asking us where Lee lived. We didn't know exactly but we have his phone number. Would that have helped you?"
"It would have been useful", I said. "I could have gotten his address from the phone company."
"Oh, I am so sorry, I should have realized that."
The claim that the CIA was closely following Oswald's seems to me to be refuted by this apparent fact. If they were following his every move, as some claim, why didn't they know where he lived? And, from what I've read, the CIA wasn't following Oswald in the US; they were receiving *reports* from the FBI about him. e.g., Jame Hosty. Who frankly did a pathetic job of it, e.g., he never interviewed Oswald and didn't even know what he, Oswald, looked like. Plus, as noted above, he didn't know where Oswald lived during the day for about two months.
