Police Chief John Weinlein III presides over the Berkeley Township Police Department, which consists of roughly 74 police officers, 10 communications operators, six records clerks, four support staff and 14 school crossing guards. Weinlein has served in the position since 2000.

The department was created in October 1954 under the direction of Police Chief Samuel L. Britton. Britton knew every family and every business owner in town, according to the township's "Welcome Brochure." The new police department building, constructed in 1978, was named the Samuel R. Britton Law  Enforcement Center in his honor in a 2003 ceremony.
