My guess is that there are probably some russians still alive that were passing info about who oswald was talking to, and what about, in their embassy in mexico.
Such folks would likely have been passing on info on many other subjects over the years.
Out of professional courtesy, we probably don’t want to see them killed.
“My guess is that there are probably some russians still alive that were passing info about who oswald was talking to, and what about, in their embassy in mexico.”
Except we already know who the source in the Russian embassy was, it was one of the part time secretaries who answered the phones who was reporting back to the CIA (and they had a surveillance camera set up across the street as well). That’s been public knowledge for quite a while now.
