Stupid video.... #1 in almost any situation is situational awareness... It does no good to run if you run into the BG... Hiding only works until you give yourself away or the shooter notices you...
People tend to panic and all chaos breaks out... Situational awareness, prior planning and calm but quick action are a good start..
Running might also mean a boy in blue thinks your a threat if you suprise the officer... shouldnt be but it might be fatal....
