People just “looked on” while a man stabbed a two-year-old child? And her mother, his ex-wife?

I hope the story is factually inaccurate — surely people were running to help the poor child and mother and just did not arrive in time to prevent the serious injuries. I wish one of the wire reports I’ve seen that describes people watching this would clarify this rather signficant detail. It is a gaping hole in every story.
