John Dillinger may have been "Public Enemy No. 1" in 1933 and '34, but Americans didn't reflexively hate him, and this hour explores reasons why as it chronicles his 14-month bank-robbing spree. Dillinger "represents a rebellious impulse that many people in the Great Depression had good reason to feel," says Tom Doherty, one of the historians interviewed. Morever, "he was a charming guy," says another, Claire Potter. The hour also features a grandnephew of Dillinger and Alston Purvis, the son of Melvin Purvis, the G-Man who finally caught up with the Public Enemy.
