OK I'm a civvie, don't know shit about how it is on the street, and I wasn't there but WTActualF?!?!

I see a complete lack of fire control discipline, a crazy number of shots fired (most at an apparent corpse) and worst of all - exactly zero awareness as a group of a significant number of innocents directly in the line of fire.
Bad day to be a civilian MYOB in Atlantic City I guess.
The "GG" front left, who appears to be wearing body armor and has a direct line of fire on the armed BG, immediately turns tail when threatened and runs away. He does this while randomly firing a string of un-aimed shots behind him in the general direction of the BG and pedestrians crossing the street. That dude would scare the crap out of me as a fellow LEO or civilian on the street. IMHO he and the whole group need to be disciplined and retrained.
My default response to getting caught in any such action - get down / find hard cover. It ain't the movies and the "GG's" here are frankly far more terrifying than the BG.
