How the "Reid Technique" can force innocent people into making false confessions

After watching “Scenes of a Crime” over the weekend, I now know why this potent documentary has garnered so much praise. Filmmakers Grover Babcock and Blue Hadaegh have interspersed actual footage from the lengthy police interrogation of an accused father in Troy, New York, with excerpts from Reid Technique training films and commentary by key players in the case. The result is a clean, careful, and gripping illustration of how a man can be manipulated into confessing to a crime he didn’t commit.
The film is especially relevant in the child abuse arena, as it also documents a hasty and inaccurate diagnosis of inflicted infant head trauma that triggers a legal nightmare. As explained in a film review by astute critic Kenneth Turan at the Los Angeles Times:
What is perhaps most remarkable about this case is the way it began. When police went to the hospital to look into the death of [Adrian] Thomas’ son, they were met by Dr. Walter Edge, who not only told them that the infant had died of a fractured skull but added, in no uncertain terms, “somebody murdered this child.”
Roused to action by this declaration, detectives looked around for likely suspects, saw one in the infant’s very large father, and turned the situation into a self-fulfilling prophecy. Armed with the zeal of the righteous, they believed nothing would do unless Thomas could be made to confess in exactly the way they thought he should. Which is what eventually happened.
At the risk of ruining the suspense, I note that Thomas’s son Matthew did not in fact have a fractured skull—nor did he show any bruising, grip marks, or other external signs of either shaking or impact—and laboratory tests later revealed a serious systemic infection, missed by not only the treating doctors but also the pathologist who performed the autopsy.
The most chilling aspect of “Scenes” is the unshakeable confidence of the police and prosecutors, who never look back even as the medical evidence unravels.
In the course of a 10-hour interrogation over two days, detectives Adam Mason and Ronald Fountain lie to their suspect—repeatedly and cruelly—threaten to target his wife, argue with him, pretend to befriend him, pray with him, hug him, and flatly reject his repeated denials.
“You want to save your son’s life, man?” Mason asks at one point, “Why are you holding out on me?”
The detectives start their investigation with two suspects, Thomas and his wife, the only adults in the apartment when Matthew’s breathing problems started. They eventually tell Thomas, falsely, that his wife is blaming him, and if he doesn’t confess they will go after her. “My wife is a good wife,” he tells them. “I don’t believe my wife did that, but if it comes down to it, I’ll take the blame for it.”
Detectives explain that he can’t just say he wants to take the blame, he has to tell them exactly how it happened, convince them that he did it.
