Delaware County’s Criminal Investigation Divison Achieves Historic Accreditation Honor
District Attorney Jack Stollsteimer today announced the Delaware County District Attorney’s Criminal Investigation Division (CID) is the first DA’s Criminal Investigation Unit in Pennsylvania to have earned accreditation by the Pennsylvania Chiefs of Police Association’s Law Enforcement Accreditation Commission (PLEACP). The PLEACP accreditation program is designed to evaluate and improve law enforcement agencies by the adherence to a thorough set of professional standards. To achieve accreditation, an agency must complete a self-assessment, comply with standards, and be verified by independent professionals. The program helps agencies improve performance, develop better community services, and potentially reduce liability risks.
