This is a highly misleading way of describing the situation.
The police set up a traffic stop to arrest them. They fled the stop. Finicum told the police he wasn't going to surrender and that they'd have to shoot him. He reached for his gun in his pocket, and then he was shot.
If black men were only being killed by police after fleeing arrest, refusing to surrender, challenging the police to shoot them, and then reaching for a gun...then we wouldn't have much of a police violence problem.
