In Minnesota, parts of Minneapolis erupted in flames Wednesday night as residents took to the streets for a second night to protest the death of George Floyd, a Black man killed by police on Monday. A video circulated widely on social media earlier this week shows George Floyd gasping for air and telling the officers “I cannot breathe,” while a white officer named Derek Chauvin pinned him to the pavement with a knee to his neck. Three other officers stood nearby. All four officers have since been fired. The officers confronted Floyd after receiving a complaint that he tried using a counterfeit bill to buy groceries.

On Wednesday, protesters held a day-long demonstration outside the city’s 3rd Precinct police headquarters. Police fired tear gas, flash-bang grenades and projectiles in an attempt to disperse the crowd. Demonstrators also rallied outside the home of former officer Derek Chauvin.

On Wednesday night, the city requested help from the National Guard as a number of buildings were set ablaze. Meanwhile, Minneapolis Mayor Jacob Frey has called on prosecutors to file criminal charges against Chauvin.

Mayor Jacob Frey: “Why is the man who killed George Floyd not in jail? … George Floyd deserves justice. His family deserves justice. The Black community deserves justice. And our city deserves justice.”

The Star Tribune reports Derek Chauvin was involved in multiple police shootings in his 19 years on the Minneapolis police force and was the subject of a dozen police conduct complaints. Protests over the killing of George Floyd have also erupted in other cities, including Los Angeles, where demonstrators temporarily blocked traffic on Highway 101.
