Look at the casual smugness of Officer Derrick Chauvin. Sunglasses casually perched on the top of his head. Knee casually crushing the life out of George Floyd. Hands in pockets as if to say, "Who? Me?" But that facial expression of Chauvin's face... the self-satisfaction, and the knowledge that he had permission from the very top. That's how I see this picture.
Others see this picture and have a different reaction. You can imagine how Tucker "Tiki Torch" Carlson, Stephen Miller, and anyone else who serves Trump react. To Republicans, this picture is porn. It's a snuff film. No doubt they carry a copy in their wallet and on their phones just so they can pull it out when they need a recharge.
