The U.S. Supreme Court has declined to review the federal civil rights conviction of a former Minneapolis police officer who held back a concerned crowd while fellow officers pinned down a dying George Floyd. The high court, without comment, on Monday rejected the appeal of Tou Thao, who had argued that prosecutors failed to prove his actions on the day that Floyd died were willful, and alleged that prosecutorial misconduct deprived him of his right to a fair trial. Thao had testified that he merely served as a “human traffic cone” when he held back concerned bystanders as former Officer Derek Chauvin, who is white, knelt on Floyd’s neck for 9 1/2 minutes while the Black man pleaded for his life on May 25, 2020.
