NSA has no interrogation capability at all. I no longer understand what you're talking about. Regardless, I feel pretty confident that what MLK and his associates faced is far worse than anything Snowden faces, at least from the US. Who knows where things will go in Russia.
Dumbest thing I've heard yet today. It reminds me of the scene in Demolition Man where Simon Phoenix cannot kill Dr. Raymond Cocteau so Phoenix enlists one of his ne'er-do-well friends to dispatch him.
If you believe in the concept of "degrees" of torture, at least. It's all wrong on every conceivable level. You don't need to ever lay a finger on someone to break their mind and leave them permanently damaged.
