It just brings out the conspiracy theorist in me, everything that is going on these days seems to be by design. Nothing has happened by accident since the 60s.
I don't think it's much of a conspiracy. It's about dealing with short-term interests at the expense of long-term interests. Immigration has and can be of great benefit to the recipient countries if the immigrants are enthusiastic about participating in their new societies, but I don't like the idea of bringing in foreign labour to fill the cheap jobs so that their kids grow up alienated and disillusioned.
As far as the riots themselves are concerned, it sounds like the initial incident is worth investigating, to determine whether the victim was indeed an armed drug-dealing thug resisting arrest. The riots, looting, assaults and vandalism are a completely unacceptable response, and they destroy the victim's family's efforts to seek justice through a proper investigation.
Whatever the outcome, and whatever changes to Britain's social structure ensue, I believe the class warfare problems will persist until the overpopulation issue is addressed. We all have to pass tests in order to acquire licenses to operate a motor vehicle on public roads, yet we are subjected to no such standards when it comes to bringing children into this world, even if some people are clearly incapable of raising their children to participate in a civil society. The social problems around the world will continue indefinitely as long as bad parents are permitted to have children.
