Kenya's Anti-Terrorism Police Unit (ATPU) is charged with preventing terrorist attacks, but in carrying out its mission the ATPU has committed a wide array of human rights abuses that violate international, regional, and domestic law. This book documents specific extrajudicial killings and disappearances to illuminate a pattern of rights abuses by the ATPU, and make recommendations for reform. Jonathan Horowitz is an associate legal officer for the Open Society Justice Initiative's National Security and Counterterrorism program. He is the author of Counterterrorism and Human Rights Abuses in Kenya and Uganda: The World Cup Bombing and Beyond.
