"Almost a third of black and Asian people fear they could be subjected to police harassment if they make a complaint against their force, a study revealed. More than a third (38%) are also reluctant to complain about assaults, racial abuse or police inaction because they have little confidence that their grievance will be taken seriously, according to the research. By contrast, less than one in five white people are worried they might be singled out and harassed if they complain and only 30% are concerned they will be ignored."
