I’ve deleted my posts about that. Water under the bridge. The real point (setting all of that other stuff aside) is what doormen are for and, in particular, whether their position as doormen increases their responsibility to act in these situations. I am not saying that they are the same as security guards, but I feel that they, as doormen, were more than simple bystanders and did have a heightened responsibility to act. Their failure to do so, though perhaps understandable given fear and shock, is not fully absolved in my mind. But we can agree to disagree on that.
(There is a whole branch of situational ethics that deals with exactly this kind of dilemma, and it does take into account things like personal risk or psychological barriers to action. It makes for interesting discussion, and I will be the first to admit that there are no easy or even “correct” answers. One way people vary the famous trolley problem is by asking, “Would it change your action if you were an employee of the rail company, rather than just a bystander?” Anyway, food for thought.)
