To be fair there has been a trend of rioting in Britain in the summer over the years - with various motivations - racism, attacking police and businesses, vandalism, looting. There are people who want to stir up mischief inciting people with vague or coded language.
Any crime apparently linked, however tenuously, to ethnic minorities is used to promote racist and anti refugee prejudices. Sadly, it's those people who are at the bottom of the pile with least stake in society who are most likely to be manipulated into this action. Actions that damage their own communities and put lives - including the police's - at risk.
The current riots and violence seem to be mostly perpetrated by white males who feel disadvantaged and alienated in society. And we do, politically, need to address this alienation and hopelessness. But in reality they are being manipulated into blaming ethnic minorities when really it's growing inequalities that is responsible.
Happily the anti-nazis and anti-racists are out in force today in many cities across the country.
The UK remains 83 percent white - we are not being overrun by foreigners. The problem is that wealth and power is being controlled by the few. And that means many people have very little hope of sharing in prosperity or having a valued role in society.
