"We always go places," said one child, whose name was not revealed. "He always teach me how to be a man. And these white racist cops got my own dad. And Black Lives still matter."

Elsewhere in the city, looters ransacked a Foot Locker, Rite Aid and other retail stores. Atleast one vehicle was set on fire.
