OK. See, I thought that it hadn't specifically been banned yet. I in fact thought that the recent brou-ha-ha was partially about the limits of interrogation.

Could you point me to a specific article that talks about what the current limits are? I'd appreciate it.

(That said, I do stand by the part where even supposedly "minor stuff" can lead to permanent impairment. Grabbing and shaking someone, particularly if they're already impaired, can lead to permanent brain damage and death. Sleep deprivation has been known to lead to psychotic breaks. And so on. It really does not compare to fraternity initiations.)
