Louisiana Prison

The Times-Picayune has come out with an 8-part series on prisons in Louisiana in which reporter Cindy Chang spent over a year researching how Louisiana became the prison capital of the world.  It's a well-researched and thorough report with special attention to a number of areas (e.g., pardons, sentencing laws and the state's sentencing commission, costs of incarceration, and economic incentives to incarcerate).  Here's the video that opens the series.  There are a number of other videos and graphs.
