“Critics of the prison-happy American criminal justice system tend to subscribe to a narrative that goes like this: Mass incarceration was ignited by the war on drugs (blame Nixon or Reagan), was pumped up by draconian sentencing and is now sustained by a ‘prison industrial complex’ that puts profit before humane treatment and rehabilitation. John Pfaff, in his provocative new book, ‘Locked In,’ calls this the ‘Standard Story.’ And he challenges every element of that narrative.”
