Clear your dead drops and check your six for a tail as this week we look at the arrest by the FBI of nuclear physicist Jonathon Toebbe and his school teacher wife Diana for attempting to sell secrets to a “foreign government”.  Who might that “foreign government” be, how did a peanut butter sandwich figure in this story, and what could have motivated the Toebbes to seek out their country for a fist full of cryptocurrency? And how did this intelligence scandal compare to the case of John Anthony Walker Jr, a US Navy Warrant office who led a spy ring that undermined US military and intelligence operations for nearly two decades? Strap in for some good, old-fashioned skullduggery as we look at why seemingly normal people turn traitor.
