Why does the Land of the Free imprison more of its population than any other nation? We're not in good company at the top of that list. Most of our peers are well below us, both in rank and in proportion. The UK has nearly six times fewer inmates by proportion. On the other hand, the world's largest democracy India supposedly only has 30 out of each 100,000 of its citizens in prison.
Just think about possible answers to that question.
