The trick is that the Trump versions of reality have collided with bystander videos watched by millions who did not see what they were told. Ms. Good did not run over the ICE agent who killed her; a video analysis suggested she was trying to turn away from him and he continued to shoot her even as she passed him. Mr. Pretti approached officers with a phone in his hand, not a gun; he moved to help a woman who was pepper sprayed and he was under a pileup of agents when one suddenly shot him in the back.
