Deaf Walls Speak presents an insider's view of artmaking in Guantanamo, the world's most notorious prison, as self-expression and protest, and to stage a fundamental human rights claim that has been denied by law and politics: the right to be recognized as human. The book juxtaposes detainee artist Moath al-Alwi's testimony and artwork with essays that situate his work within legal, political, aesthetic, and material contexts to demonstrate that artwork at Guantanamo constitutes important forms of material witnessing to human rights abuses perpetrated and denied by the U.S. government.
