It isn't just a London issue. The Muslim Somalis and Turks that Sweden took in are rioting in Stockholm. That doesn't seem to be hitting the USA news.
Stockholm Riots Continue for Third Night - WSJ.com
The news media is pulling their usual politically correct BS and describing it a "youths rioting." According to a good friend is Stockholm, none of the youths are native Swedes.

Stockholm riots challenge image of happy, generous state
We see the same media crap with the almost annual riots in Paris. It is not the French who riot and burn cars. Its the Muslims they have taken in. I am willing to bet that just like the Boston Chechen Muslims who blew up innocent people, most of these families are also living on the public dole.
The London murder would have never occurred if people were allowed to carry firearms. Someone would have blown those animals right out of their socks. The solution is not to ban uniforms, but rather to put more handguns in the hands of honest Brits.
