When I think back about this event, I feel ashamed I was part of the crowd uncomfortably watching and laughing as this guy was being sexually assaulted until it escalated into a possibly fatal situation, and only then recognized how serious this was. I'm glad I did eventually act but I feel like I waited too long, and then there was everyone else that didn't treat it seriously until the next possible victim wasn't male?
I think even after I told this story to others, especially other guys, they'd sketpically or mockingly question why the guy just didn't overpower this woman and get out of the situation himself. People can be really unempathetic or myopic.
A bit of caution is warranted in these situations. It was a different scenario but a fellow bystander and I watched a dude try to steal a woman's purse at a local mall. She wasn't having any of it and he was getting angered. The other bystander and I were basically in shock like you mentioned, but we finally glanced at each other and sorta nodded that we'd do something. As we approached them the thief pulled a gun on us. You just never know.. it could be a gun, knife, whatever. Not to mention someone on drugs or desperation will do things that you won't. Even getting a bite taken out of your face by a crazy person would be enough to instill some regret.
