valid, but I do disagree about the timing of "gun gun" and the reaction.

close inspection of the video shows the shooter initially turned around after "he's got a gun", which morphed into "Gun Gun!" at the time he started reaching for his sidearm. the video above shows the shooter started reaching before the sound of the first gunshot. in fact, the video shows the shooter reaching for his own sidearm at the precise moment the agent in grey initially grabbed Pretti's gun in it's holster well before the first shot.

I haven't been able to find any footage where the slide of pretti's gun is anything more than a blur though.
