"Published on the second anniversary of the global protests over the police killings of George Floyd and Breonna Taylor, UNREASONABLE is a ground-breaking investigation of the role that the U.S. Constitution plays in the epidemic of police violence against Black people. In this crucially timely book, celebrated legal scholar Devon W. Carbado explains how the Fourth Amendment became ground zero for regulating police conduct -- more important than Miranda warnings, the right to counsel, equal protection, and due process. Fourth Amendment law determines when and how the police can make arrests, stop-and-frisk, conduct traffic stops, and employ deadly force -- and Fourth Amendment law legitimizes the treatment of Black people as what the book calls 'runaway criminals.' Drawing on the narratives behind and the outcomes of key Supreme Court cases that everyone should know, Carbado shows how, in the last four decades, the Supreme Court has interpreted the Fourth Amendment to protect police officers, not African Americans; how the Fourth Amendment sanctions racialized policing; and how that amendment has become a body of constitutional law that manages the precarious line between stopping Black people and killing Black people. Accessible, compelling, and essential reading, UNREASONABLE offers a 'people's' account of the Fourth Amendment that sheds light on a critical but rarely understood dimension of a pressing social issue." -- from the book jacket
