Incarceration in Michigan and In America

In a recent book, The New Jim Crow, by Michelle Alexander, she presents the following statistics:

• "our incarceration practices are expensive, ineffective and based on insanity."
• "In 1965 we had one seventh of the world's prisoners."
• "Today the US has one fourth of the world's prisoners."
• "Today an African American child is five times as likely to see the inside of a jail."
