What happened in Japan was a tragedy, a natural disaster. While following the news coverage online and on cable tv, it occurred to me that what we are not hearing about events in Japan is quite important. No reports of looting, rioting, widespread criminal activity.
Contrast this to what happened in New Orleans after Katrina or Haiti after the earthquake there.
To understand a situation, look for what is seen and what is unseen.
Why is this? Culture? Civil society? Homogenous population? All of these?
