US Officer on Trial for Death that Sparked Protests Against Police BrutalityA court in the U.S. state of Minnesota proceeded Thursday with the trial of Derek Chauvin, the police officer charged in the death of George Floyd last year that sparked widespread protests against police brutality and systemic racism last year. Jurors on Wednesday saw about 20 minutes of police body camera video that spanned the time from when police approached Floyd’s vehicle and when he was loaded into an ambulance. One video played Wednesday showed Chauvin saying Floyd was “a sizable guy” and “probably on something.” Chauvin kneeled on the back of Floyd’s neck for 9 minutes and 29 seconds as Floyd cried repeatedly that he could not breathe. Chauvin, who is white, was fired by the city's police department the day after Floyd, an African American, died in custody. Jurors also heard testimony from several witnesses, including the convenience store cashier who sold cigarettes to Floyd moments before his deadly encounter with Chauvin. Christopher Martin testified that he knowingly accepted a fake $20 bill from Floyd for the cigarettes even though the money would be subtracted from his paycheck in accordance with store policy. The 19-year-old said after second-guessing his decision, he informed the store manager who told him to go outside and ask Floyd to return to the store. “If I would've just not taken the bill, this could've been avoided,” Martin said. Echoing sentiments from other onlookers, Martin said he felt “disbelief and guilt,” as he stood on the curb watching Floyd’s arrest. Martin was among several people who have testified about their frustration and anger as they witnessed Chauvin kneeling on Floyd’s neck outside a convenience store last May. The officer is facing charges of murder and manslaughter and has pleaded not guilty. Chauvin’s defense lawyers have argued he was following his training and that other factors such as heart disease and drug use caused Floyd to die. The city of Minneapolis recently agreed to pay Floyd’s relatives $27 million in damages to settle their claims of abuse in the case. Courteney Ross, the late Floyd's girlfriend testified in court noting that the two struggled with opiod addiction. She said that was not the cause of his death,
