Using Smell as part of Interrogation!

You know, he's thinking about how the suspect smells. He's talked to me about that. Like, he picks up on how - what their body odor is, what their eyes are doing, what their hands are doing and all of that is going - he's improvising - all of that is going to help him determine how to proceed in the interrogation.

. . . the best detectives that I've seen are not harsh, and the reason is that it's more effective to do what they do. And it's interesting in this environment. People want to tell them. You almost have the impression that people are kind of yearning to speak. They're just looking to be approached in the right way. So that's one of the reasons why it works. But I think it's also because, frankly, he's a very, very sophisticated interrogator who has interrogated hundreds and hundreds of people, and he knows what works. And it's the greenhorns who are harsh in interrogations.

Fascinating interview. It makes me wish I was a detective. Especially using smell as part of interrogation!
