On the evening of May 25, 2020, white Minneapolis police officer Derek Chauvin kills George Floyd, a Black man, by kneeling on his neck for almost 10 minutes. The death, recorded by bystanders, touched off what is possibly the largest protest movement in U.S. history and a nationwide reckoning on race and policing.

The 46-year-old Floyd, a Houston native and father of five, had purchased cigarettes at a Minneapolis convenience store. After a clerk suspected that Floyd had used a counterfeit $20 bill in the transaction, the store manager called the police. When officers arrived, they pulled a gun on Floyd, who initially cooperated as he was arrested. However, Floyd resisted being placed in the police car, saying he was claustrophobic. Officers eventually pulled him from the car and Chauvin pinned him to the ground for nine minutes and 29 seconds. Floyd was unresponsive when an ambulance came and was pronounced dead at a local hospital.

After video of the incident was posted on Facebook, protests began almost immediately in Minneapolis and quickly spread across the nation. Demonstrators chanting “Black Lives Matter” and “I Can’t Breathe” took to the streets from coast to coast, and police departments around the country responded with riot-control tactics. Floyd’s murder came after protests over the killings of Ahmaud Arbery in Atlanta in February and of Breonna Taylor in Louisville in March, and also came in the third month of nationwide lockdowns due to the COVID-19 pandemic.
