Well, not precisely, but I read a few books when I was getting ready for our Model Wizengamot, and one of them talked about Interrogative Technique and like Draco says, Good Auror/Bad Auror is one thing they discussed in the books.

But you should come to Future Interrogators next year, Lav! It's really much more fun than it sounds. And you can practise talking to authorities - not that we'd ever willingly get in trouble! But we'd know next time just what to tell them when we see someone coming after Harry or whatever. And not a dog, either!
