I really enjoyed Rights at Risk. Shipler covers the dark side of our criminal justice system. It's a tough but necessary read. Shipler discusses many of the bad elements: Abusive and unethical prosecutors coercing false confessions, unfair and punitive immigration laws, underpaid and unprepared defense lawyers; all of these are a part of our justice system.
The best part was Shipler's story of the young who knows the cops are framing him and won't accept the actual facts, so he manufactures a false confession--claiming he stopped at his grandfather's house when his grandfather was deceased. Both exciting and with a valuable message, Rights at Risk is a great read.
