 MISC: During the fight outside DuPonts office, John Preston drops  his two pistols (at the end of the hallway fight) and is running up  to the assault rifle (the one he flips over his head). As he is  running up to body and the rifle, you see the guards running up to  the door. Just before the the camera angle switches to the rifle,  you see the guard on Prestons right stop and take aim. After  Preston gets the rifle and takes aim, it cuts back to the two guards  and you yet again see the guard on the right running up to the door  and get shot down.
