>That seems common with public attacks.
There's a term for it that I can't remember.... that the more people witnissing something horrible the less likely someone helps 'cos of the "anonymity of crowds" sort of thinking we all have hardwired in. There's a feeling that SOMEONE will do something, but not us. (It's not actually apathy.... that'd be software. This is hardware.) That's why when you learn first aid they tell you to say stuff like "YOU! *point* call an ambulance" 'cos it overrides this trait.
