Paul Butler was an ambitious federal prosecutor, a Harvard Law grad who traded in his corporate law salary to fight the good fight. It was those years on the front lines that convinced him that the American criminal justice system is fundamentally broken - it's not making the streets safer, nor helping the people he'd hoped, as a prosecutor, to protect. In Let's Get Free, Butler, now an award-winning law professor, looks at several places where ordinary citizens interact with the justice system, exploring what 'doing the right thing' means in a corrupt system.
