This week, America was rocked by the brutal killing of Tyre Nichols. The 29-year-old Black man was killed during a traffic stop by an elite police unit made up of five police officers who are also Black. His beating in Memphis, Tennessee was viewed across the country through a series of video recordings. Nichols was laid to rest on Wednesday at a funeral attended by US Vice-President Kamala Harris, who condemned the deadly "act of violence".
