An e-mailer: “I’m sure that Mr. Ledeen could corroborate the fact that one particularly vile part of Iran’s system of imprisonment and torture is that the captives are often allowed to go home for a brief time. It allows their families and peers to see what has been to them and further spreads the horror of their torture, making it more effective as a deterrent to unapproved behavior. It also plays psychological havoc with the captives as the must walk around in freedom with the prospect of future horror hanging over their heads.”
