Since 1970, the number of incarcerated people in the United States has grown exponentially and currently sits at around 2 million people. Meanwhile in Finland, that number is around 3,000, where one third of the country’s prisons operate as open. To talk about what that means and how the U.S. prison system might be reimagined, we were joined by a WBEZ reporter who dug into Finland's criminal justice system. 

On the 21st: A rebroadcast of our interview with WBEZ Chicago's South Side reporter Natalie Moore - about her book "The South Side: A Portrait of Chicago and American Segregation." Plus, we discussed NPR's "Hidden Brain" podcast with host Shankar Vedantam.
