In February 2016, Springettsbury Township Police Department voluntarily partnered with the Department of Justice (DOJ) Office of Justice Programs Diagnostic Center.  (The 30th Police Department in the entire country to partner with them.) Per Chief Stump’s request, a team from the DOJ Office of Justice Programs Diagnostic Center and Transparency Matters LLC. spent hundreds of hours interviewing a wide variety of community members and organizations as well as reviewing Springettsbury Police Departments policies, procedures, rules of conduct, training, reports, citizen complaints, internal affairs, use of force reports, and community relations.
