In the thick of “Detroit,” a new film by Kathryn Bigelow about the uprising in that city — my native city — 50 years ago, a white cop kills a black man. His partner then asks a witness, a black man, what he saw. The witness says he saw nothing. The partner puts the same question to another witness, a black teen, who refuses to play along.
“You killed him,” the teen responds.
“I don’t see anything,” the cop says.
