Why would they put high value prisoners at a minimum security women's prison?
Maybe, but the folks we're talking about are a lot higher value/risk than the martha stewart types. Last time they had espionage-level female prisoners was the 40s and 50s. Granted, it's out in the relative boonies, so with a complete change of personnel, maybe.
