The responses of two prime ministers to public violence is culturally significant is several ways.
Jens Stoltenberg was reflective, David Cameron punitive.
The Norwegian kept going onto the streets to embrace suffering citizens; David Cameron retreated behind well-planned photo opportunities.
One announced strong support for a clearly flawed police force; the other issued critical and destabilising statements.
One declared a public inquiry, the other refused.
One sought moral clarity across the whole of society, the other took refuge in class condemnation.
In Norway, there is unity, in Britain division.
It is not too late for David Cameron to change his way of dealing with the post-riot landscape. Unless he does, he will look increasingly a lame duck prime minister.
