Memphis police have revealed a sixth and a seventh officer have been placed on administrative leave in addition to the five fired officers over the death of Tyre Nichols, after Nichols was brutally beaten at a traffic stop.

His opinion piece for The New York Times is headlined “Tyre Nichols’s Death Proves Yet Again That 'Elite' Police Units Are a Disaster.”
