Thanks Mia, glad you enjoyed the post. I will have a look/listen to the link you shared, it is an interesting phenomenon.
I’ve amended the blog to show how the incident was sensationalised and incorrectly reported.

It was the incident that brought the ‘bystander effect’ into the public domain though. And whilst the numbers weren’t accurate, I think the lack of action from several witnesses still emphasises diffusion of responsibility – albeit in an extreme case.
