As quoted on TV (DC channel 9 - CBS), I pointed out that a four thousand pound vehicle moving at five to ten miles per hour has a lot more kinetic energy than a bullet. When one of those hits you, you don't stand much of a chance. And she'd begun accelerating once she got out onto East Street.
Peter Nap's observation about firing enough to stop the threat is consistent with the officer's training. That's why there were still eight rounds in the magazine when the VSP took the gun.
Sawah's observation about the question of whether or not the officer's hand was actually and irretrievably pinned by the side window glass is interesting. Is that a crucial point for the entire episode, or only for the first part, prior to his having shot out the glass?
I have been following this thread for a while but have not really had anything of worth to respond to until now. The idea of comparing a vehicle's energy and a bullets energy without regard to the size of the contact point, ie pressure per square inch makes the comparison nonsensical when determining how deadly the impact would be.
ie, nonsense.
I have nothing else to argue with.
