Elizabeth Hinton's - America on Fire: The Untold History of Police Violence and Black Rebellion Since the 1960's is a fascinating, well-documented, detailed book that I highly recommend! Hinton tells the story of how, despite documentation of systemic racism and laying out how things needed to change was made in things like the 1968 Kerner Report, little has changed for Black People's safety from the police. White politicians, police unions and the active and passive resistance of white people have strongly kept racism alive over the past 50+ years. Since the 1960's there has been a massive buildup of powerful weapons as part of a militaristic strategy that has resulted in Black incarceration rates soaring. huge financial investments, while white racist actions are excused and police over-reactions are justified as being the right path. Police killings of Black People as well as blaming Black People sustains Black resistance and makes bad situations much worse.
