Actually none of them were witnesses to what happened they had ran away to save themselves. No one knew what Gin did or his motivations for anything that took place. The only who came close was Rangiku and she herself admits later after Aizen is defeated that she never really understood his actions. In any case it seems everyone is left to believe that Aizen decided to kill him for no other reason then just because as far as they know. Also just to point out his failed attempt at attacking Aizen doesnt absolve him over 110yrs of manipulation, assault, murder & betrayal.
