Sudhir Venkatesh

Today we spoke with Sudhir Venkatesh. As a sociology student in Chicago, he went to the projects with a questionnaire that said, among other things, how does it feel to be black and poor?

The men he met laughed at him ... and detained him in a hallway while they cut drug deals. Out of that inauspicious start came the riveting book about his years studying (and befriending) dealers, Gang Leader for a Day.

The book has caused a lot of controversy. A blog called Marginal Revolution gave the book a thumbs down because they felt Venkatesh was encouraging or at least condoning the drug dealing.

The author of the bestseller Freakonomics wrote a rave review of the book.

Take a listen to our interview. Do you think Venkatesh was condoning dealing, doing good research ... or a little bit of both?
