I love how their reaction was to try to go to help her, but the code for them to stand there and wait for the gun shots over rode it. It's like how you can get the cops in GTA V during certain missions to want to shoot you, but then they suddenly freeze up and can't because of the mission parameters overriding their behavior. That happens mostly in certain missions (*can't recall which ones immediately...) where you can steal a police car and the officer makes for his gun, then immediately goes back into standing mode. Because the code won't let him shoot you or attack you at the time.
