The first part of this report is an update to Amnesty International's 2015 report Deadly Force: Police use of lethal force in the United States, which reviewed state use of lethal force laws in all 50 states and Washington D.C. The second part of the report focuses on the policing of protests that have occurred in cities across the USA since the death of George Floyd in Minneapolis, Minnesota. Amnesty International reviewed over 500 videos of protests and documented 125 separate incidents of police violence against protestors in 40 states and the District of Columbia between May 26th and June 5th of 2020. This report also draws on Amnesty International's interviews with 50 individuals, including protestors, journalists, legal observers and street medics, and a review of media reports, medical reports, photos, and videos. Conclusively, there is a disturbing lack of progress in the last five years in ensuring that police officers use lethal force only when there is an imminent risk of death or serious injury to themselves or others.
