Should the U.S. reconsider negotiating for hostages?

In “We Want to Negotiate: The Secret World of Kidnapping, Hostages and Ransom,” author Joel Simon analyzes hostage situations involving Westerners taken from Syria. One example: American journalists James Foley and Steven Sotloff, who were executed. Judy Woodruff sits down with Foley's mother, Diane Foley, and author Simon to discuss why the U.S. might need to reconsider its negotiation policies.
