"Your character is not bad. This doesn't sound like the kind of thing you would do. Going back to your character, you're not a guy who's on the street. You're not on the street gangbanging, shooting and robbing.... You're a good, hardworking guy."

Ever watch First 48 ? Interrogations are nothing like TV drama interrogations. Rarely confrontations.
The detectives usually sympathize with the perp, befriending him, convincing him he just lost it in the heat of the moment. Even holding the perp's hand sometimes.
It's amazing how some of the most hardened criminals break down and fall for it.
You're watching this and saying to yourself,'is that cop nuts? This guy needs the needle!' but he got the confession.

I really like that part of 48. The sympathy talk with questions like,
Oh, he pulled the gun and it went off? Well that sounds like self defense.
Then 1st degree murder charges follow.

I've watched it before. There was one episode where the Memphis Homicide Detective Sgt. Caroline Mason asks a suspect something along the lines of, "What would you tell your mother about what happened? How would you explain it?" Really soft, like she was taking on the role of his mother.

Worked like a charm. The suspect broke down and confessed.
