This afternoon on CNN, Brooke Baldwin shared the frustration that many people are feeling about the U.S. military’s role in Afghanistan, as young soldiers and Marines are killed by Afghans they are training. Baldwin interviewed Greg Buckley, a New York man whose 21-year-old son, Lance Cpl. Greg Buckley, Jr., was shot dead last month by an Afghan police officer while he was working out in a gym.

Buckley recounted how his son told him, “‘I’m telling you, dad, they’re going to kill us. We all talk to our superiors and they push us to the side and say, don’t worry about it, we’ll take care of it.’ But they didn’t take care of it.”

Baldwin, choked up, added: “Greg Buckley, it is tough to put into words. And I’m angry with you, and I’m sad with you. Thank you.”
