Secretary of State Hillary Rodham Clinton convened an Accountability Review Board for Benghazi to examine the facts and circumstances surrounding the September 11, 2012, killings of four U.S. government personnel, including the U.S. Ambassador to Libya, John Christopher Stevens, in Benghazi, Libya. A series of attacks involving arson, small-arms and machine-gun fire, and use of rocket-propelled grenades, focused on two U.S. facilities in Benghazi, as well as U.S. personnel en route between the two facilities. In addition, the attacks severely wounded two U.S. personnel, injured three Libyan contract guards and resulted in the destruction and abandonment of both facilities. This book examines whether the attacks were security related; whether security systems and procedures were adequate and implemented properly; the impact of intelligence and information availability; whether any other facts of circumstances in these cases may be relevant to appropriate security management of U.S. missions worldwide; and finally, whether any U.S. government employee or contractor, breached her of his duty.
