I think after events like this we don’t always behave how we would expect. I’m also wondering if it’s partly down to how you might have been socialised, as a woman? We’re often socialised not to hurt others, even if they’re hurting us. I’m just speculating a little, though.
I went to a public library a couple of years ago, for a self defence class. Some dude sneaked up on me from behind a bookshelf and took a photo as I happened to look up from my book. I felt like my privacy had been invaded and really feel, when I look back, I should have reported him to staff as it was a creepy thing to do, and he kept leering at me the whole time I was in the class. But I said nothing (aside from texting a friend and sister in law about it) as I wasn’t sure whether the staff would do anything about it, and what if they’d been able to look at his phone and not found the picture? I don’t think about it as much now but it still bothers me. I get I’ve probably had my photo taken without my knowledge anyway, but it’s a different story when people literally single you out and make it obvious that’s what they’re doing.
