Why have prison populations exploded? Yeah, we bet you have an opinion on this. But we’ve got someone on the show with the math: Fordham law prof and empiricist extraordinaire John Pfaff. Everything you think you know about our staggering levels of imprisonment are probably wrong. Also, we offer to set up the Supreme Court audio live stream. Also we report on one listener’s Oral Argument power rankings.
