Black people were ten times more likely to be searched than white people in 2018/19. Reducing 'no suspicion' searches will direct police resources into more effective areas, such as intelligence-led policing. Evidence suggests stop and search has a marginal impact on crime reduction, is damaging to police community relations and can have a detrimental impact on effective community policing - searches more often find low level drugs.
