Or how about the guy with the video camera fifty yards away. Or the kids in the house just outside of the camera’s field of view. Or, it if were the lady six blocks over, what if he ran six blocks over?
There’s a reason the common law allowed cops to shoot fleeing felons. It’s because they are potentially dangerous to other people. SCOTUS has apparently narrowed the law but the basic principle is still there.
There is a reason why the Supreme Court has ruled that the police may shoot fleeing suspects only if they are representing a threat to the life and safety of the officer or of bystanders. It's because police do not have the power to be judge, jury, and executioner for anyone they choose. There was no justification for shooting Scott. Zero. Zilch. Nada. The reason why he is dead is because he ran into someone who was trigger happy and likely should not have been a police officer to begin with.
