Outlaw Platoon Author on Afghanistan Massacre

This week, I sat down with former Army Ranger captain Sean Parnell for a conversation about his new book, Outlaw Platoon.

I began our conversation by asking him about the U.S. soldier's deadly rampage in Afghanistan over the weekend.

The full conversation airs Monday March 26th on PBS.
