The Russian government's recent arrest of American Paul Whelan and its charges against him have many politicians and pundits speculating about the possibility of an intended spy swap for Maria Butina. There's a lot going on here, but there's also a lot of misunderstanding about the history of spy swaps, what they are, and what they aren't. Earlier this week, David Priess sat down with his former CIA colleague John Sipher to talk about it all. They discussed the history of spy swaps, the current case involving Paul Whelan, and prospects for some kind of a release.
