I will repeat, for the third time: Perhaps the officer who shot Pretti observed Pretti appearing to reach for what might have been a weapon (but what turned out to be a cell phone).
I will repeat, again--people who carry one deadly weapon frequently carry more than one deadly weapon.
Look, watch the videos. It looks like the ICE that took the gun off Pretti had an accidental discharge with Pretti's P320. P320s are known to have this problem. (I can't see his hand move, but you could hear the discharge.) This seemed to precipitate all the firing. There is also a report that someone yelled, "Gun, gun, gun", at around that time, but I can't hear it. Your speculation is uninformed and made up.
