London policemen have to report statistics showing a smaller proportion of black and muslimlike people being stopped and searched in the street, which leads them to do so randomly with white people, just to keep racial balance and out of political correctness, regardless of whether they seem to correspond to the targets of the antiterrorism policy.
Now, looking at it under another angle, one could rightly argue that producing such racially balanced statistics, even if they are rigged and don't lure anyone, will contribute to a more peaceful social atmosphere and, perhaps, defuse tensions and resentment that lead to some forms of criminal activities and maybe to terrorism, who knows.
