On Monday, Attorney General Eric Holder announced that he is reversing policy and will allow Khalid Sheikh Mohammed and his alleged co-conspirators to be tried before military tribunals at Guantanamo Bay. How important is this change? Why is Gitmo a better location and system than in federal court? What has the U.S. lost by debating this policy for the past few years? And does this mean the debate over closing Guantanamo is over for the foreseeable future? We ask retired U.S. Army Gen. Paul Vallely. We also get his thoughts on the mission in Afghanistan as riots and tough fighting continue there almost 10 years after 9-11.
