In the fight against terrorism, the American military's escalating drone program has become the face of our foreign policy in Pakistan, Yemen and parts of Africa. And while the use of un-manned drones indeed protects American soldiers, the growing number of casualties -- which include civilians as well as suspected terrorists -- has prompted a United Nations investigation into both the legality and the deadly toll of these strikes.

On the next Moyers & Company, Bill explores the moral and legal implications of using drones to target our enemies, both foreign and American. His guest include Vicki Divoll, a former general counsel to the Senate Select Committee on Intelligence and former deputy legal adviser to the C.I.A.'s Counterterrorism Center, and Vincent Warren, Executive Director of the Center for Constitutional Rights.

Also on the show, Rolling Stone's Matt Taibbi on the continuing lack of accountability for America's big bankers.
