As you may well know, US citizen Paul Whelan was arrested in Moscow last month and charged with espionage for being in possession of a flash drive that allegedly contained a list of employees from a Russian security agency. I had speculated that given the amount of weirdness in this case, Whelan was either a Russian asset or a convenient, useful idiot being held by the Russians who are hoping to exchange him for either Maria Butina or arms dealer Viktor Bout.
