I was just reading the latest on the Jo Yates murder here www.dailymail.co.uk/news/article-1349505/Jo-Yeates-murder-suspect-arrested-sobbing-tip-anonymous-caller.html
What would you do if you heard a scream, or someone crying "help me"? I know I would ring the police because one night just as I was going to bed I heard a very brief and very loud scream from what sounded like a girl, she said "No no no no!" in a scream and then there was nothing. I dialled 999, they told me not to go out and investigate, and came round later to tell me that they had found her and she was fine. They said they would always rather be called in these sort of circumstances, even though most of the time there is nobody needing saving, because the times when they do need to step in make it worth it. It seems that a significant proportion of the population would do nothing. I'm not judging, just wondering why you wouldn't pick up the phone.
