Opponents of the Guantanamo Bay Detention Center argued for closure of the facility. They talked about the impact of the prison on U.S. credibility, the number of trials held in the 11 years the prison has been open, bills passed by Congress that prevent the release of prisoners, and the legitimacy of military commissions. They all criticized President Obama for failing to close the facility and for not vetoing a 2012 defense bill that barred the transfer of detainees. Morris Davis in his remarks said that Guantanamo Bay had served as “a warning light rather than a guiding light” to the rest of the world.
