Dozens of protesters angry about the beating death of Tyre Nichols by Memphis, Tennessee, police officers marched through the city's downtown on Saturday. They chanted, "Say his name, Tyre Nichols" and "Whose streets? Our streets." At one point, protesters surrounded a Memphis police squad car and taunted the officer seated inside. At another, they cheered after learning that the Memphis police chief had disbanded the city's so-called Scorpion unit.
