We recently solicited your questions about street gangs for Sudhir Venkatesh, the then-grad student we wrote about in Freakonomics who is now a professor of sociology at Columbia. His answers are, IMHO, fascinating. Your questions were really good, too; thanks. Venkatesh will publish a book, Gang Leader for a Day, in early 2008.

Q: Do you think the HBO series The Wire gives an accurate portrayal of gang life? It is clear from the show (if it is as real as it seems) that traditional policing strategies are very ineffective.

A: I am a huge fan of The Wire. I actually watched Season Two with a group of high ranking gang leaders/drug dealers in Chicago, who desperately wished that the series producers would make a separate show about Chicago! Everyone in the room agreed that the writers did well to show the nuances in the underground economy.
