The New Bedford Police Department still needs to do more to increase accountability and transparency, according to a consultant’s report released by the city on Wednesday. The 71-page report by 21st Century Policing Solutions found that the NBPD has failed to increase the enforcement of transparency and disciplinary policies related to the narcotics and internal affairs departments. Among the reforms recommended: providing the community with “performance metrics” for the narcotics unit; strengthening policies on confidential informants; and barring the use of underage informants. The report by 21st Century Policing Solutions comes after the Boston Globe’s reporting earlier this year chronicled abuses by NBPD. And isn’t the first critical evaluation of NBPD confidential informant enforcement policies.
