The killing of Minneapolis forgery suspect George Floyd shocks the conscience at a level above even the immediate, righteous revulsion against a wanton act of brutality.

Upon further reflection, what tears at the guts of a viewer is more than just the casual viciousness of officer Derek Chauvin, who brutally pressed his knee against Floyd’s neck. What is far worse is the complete indifference (indeed, the tacit approval) of the other three officers on the scene. This is especially true of officer Tou Thao, the one on camera trying to shoo away the onlookers pleading for Floyd’s life.
