The one thing that is leading me to "fake" is the reaction of the news chick. Damn near every female I know, and "talking head newschick types" especially would sit there stunned and shocked. Perhaps start yelling for help, or maybe break down, but not a ONE would run TO the scene, at least not without a camera.
Most chicks and "newspeople" won't "run towards the sounds of the guns" as it were. They'll hang back and watch others help.
Funny and cringe-worthy vid, but her reaction is so unbelievable, IMHO.
