“Why are the pansy Brits not doing anything about this?”
Because the people in office and from the major parties actually derive their power from having a populace that is continually being beaten and raped. It’s a means of control, and it is quite effective.
The people that actually would take action against these crimes (like putting these criminals away for decades) are usually booted out of politics, usually by being labeled as racists. It’s like that all through Europe. That’s why that guy in Norway felt he had to take direct action to deal with their problems.
There will be a point in time where certain members of the public will say "ENOUGH!" and begin to take matters into their own hands, handing out vigilante "justice."
I recall reading an article in a British motorcycle magazine (I think it was "Fast Bikes") where motorcycle owners were sick and tired of having their motorcycles stolen. The magazine did a "ride along" with a couple of vigilante bike owners, most of whom had at least 1 motorcycle stolen within the last year. They parked in an unmarked van near a parked, decoy sportbike. Within a few hours, a couple of guys in a van stopped by and began the process of stealing the bike. The guys (in masks) jumped out of the van and proceeded to break the arms and legs of the thieves using pipes and tire irons, leaving them bleeding on the street.
Eventually the same will happen the the "Asian youths."
