A new piece of research published by Insa Koch (Visiting Professor in Law and Anthropology at the LSE), Patrick Williams and Lauren Wroe finds the development of drug policing strategies to identify those ‘at risk’ of involvement in ‘county lines’ targets and stigmatises young Black men. ‘County lines’ entered the UK policy agenda as the culmination of local ‘problem profiling’ and ‘mapping’ work carried out under the failed Ending Gangs and Youth Violence (EGYV) programme and other former drug policing and anti-gangs policies. There is a similarity between county lines cohort lists and the Metropolitan police’s discredited Gangs Matrix which the Met agreed to overhaul, removing over a thousand names, after the launch of a legal challenge last year claiming breach of private and family life rights and race discrimination .
