Hmmmm... This situation is disturbing for me, but not because of what those two men did. My first thought is that by publicizing their behavior, they are receiving attention they do not deserve. When people do despicable things like this, the best reaction is to NOT react; to demonstrate that their action is completely unworthy of attention. Removing the men was an excellent decision.
BUT (and this is the part I am disturbed by), no one can predict exactly HOW insane, or despicable these men might be, and to what extent(s) they might go should they make a choice to take their conviction to a 'next level'. THAT is what I find most disturbing.
There is nothing any of us can do to try and predict what might have additionally happened. None of us have any control over what we cannot be certain of.
Still, there will always be opportunity to contribute to what we CAN control. For example, I would hope that anyone who overheard that woman's distressed phone call, stepped up to tell her that they would act as her escort out of the theater, and stay with her until she was safely en route to her home. In addition, I would hope that they would seek out others in the theater to assist as additional escorts, in an effort to saturate her with a sense of security and safety.
We can't control the unpredictability of people like those two men, but that fear of the unknown shouldn't stop any of us from acting on the things we CAN control. New Yorkers in particular have proven, in the past, how quickly they will step up, band together, and do what's right when called upon to act for good.
