Interrogation Impersonation.

Here's an angle to watch in today's stories about the ACLU release of FBI e-mails describing interrogation techniques used on detainees at Guantanamo Bay: Military personnel apparently posed as FBI agents (who were evidently the "good cops" in the scenario) in an effort to wring more information out of prisoners. A Pentagon spokesman tells the AP that impersonating other federal agents is, ahem, not on the approved list of military interrogation techniques.
