Jennifer Bryson, who was an interrogator at Guantanamo Bay, explains why "enhanced interrogation techniques" actually sabotage interrogation:
A moment of violence might provoke a quick response, but the response is likely to be one of defense—doing, saying anything, no matter how false, to stop the violence—and a jolt in response to violence may at best only skim the surface of an individual. Interrogation is different altogether. An interrogator seeks depth and breadth of information. Getting to such depth and breadth requires finding a way to create an opening in the internal web of the detainee’s person. Perhaps an insecure young man craves having someone treat him with dignity. Perhaps a lonely detainee misses the attentive care and wisdom of a favorite aunt. Perhaps a proud warrior wants to feel respected for how hard he has fought for his beloved cause. These are the types of emotional openings a skilled interrogator can home in on and then build from in order to form a connection between the interrogator and the detainee.
