How going to war brings out the best and worst in people

Our guest Sebastian Junger is not a military veteran. He makes that clear, but he sure sounds like one. Maybe it's because he's seen more conflict than many in the United States military. If there's an expert on modern warfare and the long-term effects of those who live it, that person is Sebastian Junger. He joins us to discuss his new PBS documentary airing on Memorial Day "Going To War" and explains how people transform before, during and after combat.
