Miranda v. Arizona · ¶26

“... In this technique, two agents are employed. Mutt, the relentless investigator, who knows the subject is guilty and is not going, to waste any time. He’s sent a dozen men away for this crime and he’s going to send the subject away for the full term. Jeff, on the other hand, is obviously a kindhearted man. He has a family himself. He has a brother who was involved in a little scrape like this. He disapproves of Mutt and his tactics and will arrange to get him off the case if the subject will cooperate. He can’t hold Mutt off for very long. The subject would be wise to make a quick decision. The technique is applied by having both investigators present while Mutt acts out his role. Jeff may stand by quietly and demur at some of Mutt’s tactics. When Jeff makes his plea for cooperation, Mutt is not present in the room.”
