Not sure how this will play out where it occurred but last time I checked, if the perp (that probably needs shooting) is running away, best not shoot. Of course circumstances would dictate the appropriate response. Such as, was he steering towards one of the brothers?
Re-read the article. He was trying to flee IN THE CAR, rammed one, then was shot. If I read correctly, he was still in car, obviously posing a threat while ramming car o flee.
