Dwayne “The Rock” Johnson decried the “ongoing disease” of racism and police violence as he became the latest high profile figure to express outrage over the death of George Floyd.

The wrestler-turned-actor wrote on Instagram Thursday that he was “stunned trying to make sense” of Floyd’s death. Floyd, a Black man, died in Minneapolis on Monday after he was handcuffed and a police officer knelt on his neck.

“I’ve had cops in my family. Good men,” wrote Johnson, noting the “cop code” grants officers ”the authority to use force if your life is in danger.”

“But when a man is handcuffed, on the ground, no longer a threat, with your brothers in arms standing around watching and he struggles to say, ‘please I can’t breathe’ when your knee is on his neck, not his back, but his neck — cutting off his air. Cop code must become moral code. Ethics code. HUMANITY code,” he added.
