JOHANNESBURG — The footage is shaky but unmistakable. A slender black man dressed in a red T-shirt, black pants, and sneakers is tied to the back of a police truck. He kicks. He writhes. The vehicle pulls away, dragging the man behind it. Police officers run along with him. Cellphone cameras snap away.
“What did he do?’’ bystanders shouted.
