An asset inside the FBI would be considered so precious to the Russian intelligence agency that they almost certainly would not reveal this information to another state. Especially not a rogue state like Iraq or Libya which Russians would likely view as a tool to be used but not a trusted ally. Dear Dr. Thies, How in todays world of espionage can something like this get past all of our so called experts. Both the FBI and the CIA have counter-intelligence units whose job is to watch for betrayals like that of Ames and that alledged against Hanssen. But even experienced professionals can be misled for a time and someone who is exceptionally well placed like Hanssen was can elude detection for many years.
All government operations are fallable.
And no matter how hard one tries to prevent them mistakes occationally occur. In the Ames case, Rosario Ames was complicit in that she knew what her husband was doing. In the Hanssen case, it is too early to tell if the family even knew what he was allegedly doing. Smart, tough-love advice on relationships, family and work. Talk to newsmakers and reporters.
