The following article points strongly to the fact that the gunman was acting out of frustration due to his religous beliefs.. In other words, he was a somewhat fanatical radical moslem.

Fanaticism, whether religous, political or whatever always leads to violence. Always has, always will. It is the nature of the beast.

There is a lesson in there if you can look at it.
