I've written about illegal immigrants in the United States; I spent a year following migrant farm workers as they were harvesting. I've written about our criminal justice system, and how it treats the victims of crime. I've been working for years now on a book about prisons in America, and I've been going into prisons and traveling around the country and seeing what's going on.
