Even if they should've taken him down, once he went for it in the vehicle it justifies the shooting.They aren't being very clear. Was it in the floor of his car when they tried to arrest him? If so, he wasn't armed, and they should have taken him down instead of letting him walk to his car. If he was holding the knife, that would be very different.
Didn't they also fail in an attempt to take him down on the passenger side?
