Thank you for letting me know — this event didn’t make it into my news feeds, so I was unaware of it. I’m updating the article to include my thoughts about this, and I really appreciate you bringing it to my attention. I have looked into and have found quite a few reports digging deeper into the claim that no one responded, all of them referencing the Kitty Genovese case, interestingly. I find this CNN article to have a really well-considered take: https://www.cnn.com/2021/10/19/opinions/philadelphia-train-rape-bystander-effect-filipovic/index.html
