- Partnership/Ownership/Membership – Southeastern Massachusetts Law Enforcement Council (SEMLEC)
The Halifax Police Department is a member agency of the Southeastern Massachusetts Law Enforcement Council (SEMLEC). Like other Law Enforcement Councils (LECs) in Massachusetts, SEMLEC functions to increase regional collaboration between police and sheriff's departments, while organizing SWAT teams and obtaining military equipment for use by its member agencies. Set up as non-profit professional organizations, LECs have attempted to restrict public knowledge of their activities and have refused public records requests.
