The Police Department is headed by Chief Thomas McEnaney and Deputy Chief Walter Shea. The department's mission statement reads: "The primary purpose of the Westford Police Department is to provide a high level of safety, security and service for all members of the community ... A large suburban society free from crime and disorder remains an unachieved ideal. Nevertheless, consistent with the values of a free society, it is the primary objective of the Westford Police Department to as closely as possible approach that ideal."
