Here is the thing I don't understand about the George Floyd incident and it's pretty simple: at 8:22 pm an officer on the scene called dispatch to request an ambulance. However, Officer Derek Chauvin was still applying pressure to the back of Floyd's neck with his knee, and he did not remove his knee from Floyd's neck until 8:28 pm, a full 6 minutes (the times per the Darnella Frazier video) after an ambulance had been called. So, at least one officer on the scene realized that Floyd was unresponsive and in need of medical assistance, so why didn't anyone tell Chauvin to get off of him? Six minutes passed by and yet, there is Chauvin still resting his weight on Floyd's neck while Floyd's eyes are closed, with Floyd not moving a muscle.
