Indeed. I have no idea how I would react if I was put into that situation. I'd like to think I would intervene, but I can't be sure I would.
As a teenager I was haunted by the Kitty Genovese case
https://en.m.wikipedia.org/wiki/Murder_of_Kitty_GenoveseIn the main this came from reading Harlan Ellison about it whose reaction was affected by the original article referred to in wiki.
I think that it's dependent, as the Hinsliff article covers, on what anyone knows at the time and whether they are in a position to intervene in different manners. I've intervened in a couple of events, none as serious as this, but if I had a child with me at the time as the French witness did, I think that would definitepy have had an impact.
