Controversy has arisen regarding U.S. treatment of enemy combatants and terrorist suspects detained in Iraq, Afghanistan, and other locations, and whether such treatment complies with U.S. statutes and treaties such as the U.N. Convention Against Torture and Other Forms of Cruel and Inhuman or Degrading Treatment or Punishment (CAT) and the 1949 Geneva Convention. This book summarises the results of the review conducted by the Department of Justice (DOJ), Office of the Inspector General (OIG) regarding the Federal Bureau of Investigations in Guantanamo Bay (GTMO), Afghanistan, and Iraq. The focus of this book was whether FBI agents witnessed incidents of detainee abuse in the military zones, whether FBI employees reported any such abuse to their superiors or others, and how those reports were handled. The OIG also examined whether FBI employees participated in any detainee abuse. In addition, the authors examined the development and adequacy of the policies, guidance, and training that the FBI provided to the agents it deployed to the military zones.
