George Floyd was violently resisting arrest, and then *asked* to be down on the ground instead of in the car. Also, he was most likely killed by the enormous quantity of fentanyl in his system, not the police.
Jacob Blake was armed with a knife, resisting arrest, and about to enter a car that had children in it. Do you know what that adds up to? A hostage situation *with children*. Does that sound like a good plan to you? Just let an armed violent criminal drive away with children?
