An unprecedented work of civil rights and legal history, Presumed Guilty reveals how the Supreme Court has enabled racist policing and sanctioned law enforcement excesses through its decisions over the last half-century. Police are nine times more likely to kill African-American men than they are other Americans-in fact, nearly one in every thousand will die at the hands, or under the knee, of an officer. As eminent constitutional scholar Erwin Chemerinsky powerfully argues, this is no accident, but the horrific result of an elaborate body of doctrines that allow the police and, crucially, the courts to presume that suspects-especially people of color-are guilty before being charged. Today in the United States, much attention is focused on the enormous problems of police violence and racism in law enforcement. Too often, though, that attention fails to place the blame where it most belongs, on the courts, and specifically, on the Supreme Court. A "smoking gun" of civil rights research, Presumed Guilty presents a groundbreaking, decades-long history of judicial failure in America, revealing how the Supreme Court has enabled racist practices, including profiling and intimidation, and legitimated gross law enforcement excesses that disproportionately affect people of color. For the greater part of its existence, Chemerinsky shows, deference to and empowerment of the police have been the modi operandi of the Supreme.
