I think you are unjustifiably harsh in your judgment of the people on the bus. After all, the attack had happened, the victim was clearly dead, and wisdom tells one to avoid more bloodshed by getting out of the way.
I think my harshness is directed more at a culture that seems to be encouraging a passiveness in people and a reliance on the false security of 'rescue' by agents of the state (who, by the way, have no responsibility to provide protection to individuals)when goblins or other nasty things arise.
Even so, one concealed carry gun, one shot, and the kid being stabbed may have lived.
Yours,
