..i saw the video..as I've read a few posts before we do not know who the suspect or why he was running away. forgetting that this in itself could give us an extra hand to understand why the situation has ended so, it must be said that the "weapon" of the suspect was his car. violated the rules of the road did not stop during the chase then for the agents could carry anything or hide weapons, drugs, kidnapping someone, you have to consider many things we do not know .. in the end despite the crash test flight and of course I personally would have done everything to avoid that continues to make victims as the type of the car rammed .. even I would have shot with the weapon ready to use and I think that is not lethal .. maybe I would not have shot to kill, I'd rather shoot warning shots and then a non-lethal parts .. in this case I think they have targeted to bring it down ...
