This joint response to the Home Office review of data-sharing for migrant victims and witnesses of crime by FLEX and partner organisations raises concerns about its failure to address the findings of the police super-complaint and call from migrant sector representatives to stop using data from victims and witnesses of crime for immigration enforcement purposes, despite the consistent evidence that this practice leaves those with insecure status too fearful to come forward, prevents victims from reporting crimes, and empowers exploiters and other perpetrators of abuse.
