UK Met Police Gangs Violence Matrix
Gangs Violence Matrix (GVM , or Gangs Matrix ) was a c ontroversial system detailing thousands of alleged street gang members in London, UK. Established in 2012 in the wake of the 2011 London riots as a watchlist of people designated by police as “gang nominals”, the GVM was d eveloped and operated by London's Metropolitan Police Service ('Met Police'). The system u se d one or more algorithms to rank and categorise people included on the database, based on the risk each 'gang member' pose d to others, and the extent to which the police and partner agencies interacted with that person. The GVM w as subject to multipleresearch studies, investigations and legal reviews by Amnesty, Liberty, StopWatch and other rights organisations. The MPS scrapped the Gangs Matrix in February 2024 , replacing it with an adapted "violence harm assessment" (VHA) approach, which the Met described as more "precision-led".
