To clarify my reference to the witness stand, imagine the driver has already run over a bunch of old ladies on the sidewalk at Bingo night and is driving away screaming, "Now I'm going to get the ones at Saint Anthony's!"
Even if I shot the guy and stopped his attack, there would be a lot of innocent blood on the ground.
O.K. I didn't quite catch where you were coming from first time around.
BTW: I dig the Sig226. That's my primary firearm. When I pull the trigger I want the damn thing to fire!
