Alone at a time of danger

In this article, “Alone at a time of danger”, Peter Sidell criticizes the attitude of Japanese citizens toward affairs. To persuade his opinion of us he used two examples, the first one is “The murder of a young woman in Kawaguchi City, Saitama” and the second is “The affair of a raped young woman in Osaka”.

In the first example he questions two points.
1. Why did the neighbors do nothing to help the woman even though they heard her
screaming and a loud banging?
2. Why a coworker took two days to find the woman’s body even though he was
afraid that he has lost contact with her for a few days. Shouldn’t he have
　 reported to the police or checked if she was ok soon?

In the second example he questions a point.
Why did the affair happen even though all passengers on the train where the
woman and the man were looked on what happened?

By questioning these points, he blames the attitude of Japanese citizens toward affairs, saying “Is it too "troublesome" or "inconvenient" for people to help each other?”, and blames that Japanese society makes a point of just “the group” rather than “individual life”.
