- Partnership/Ownership/Membership – Greater Boston Police Council
The Brockton Police Department is listed as a full member of the Greater Boston Police Council, a "law enforcement council" (LEC) set up in the 1970s to link regional police forces and share resources for policing anti-war protests. LECs in Massachusetts have played a central role in militarizing police by organizing SWAT teams and purchasing military equipment such as Lenco Bearcats and other armored vehicles.
- Association/Collaboration – IBM
As of 2016, the Brockton Police Department was sharing and accessing information through COPLINK, a surveillance and criminalization platform developed by IBM and the software company i2, which has been called “Google for police officers." Through COPLINK, Brockton Police officials share their field interviews along with arrest, complaint, accident, and citation reports with other departments who utilize the platform in MA and nationwide, and Brockton Police officials are able to access the field interviews and arrest, complaint, accident, and citation reports of these other police departments. Agents from US Immigration and Customs Enforcement (ICE) "have direct access to the Massachusetts version of the COPLINK system," enabling ICE agents to access any information Brockton Police officials enter into COPLINK and utilize this information to facilitate ICE's regime of tracking, detentions, and deportations of Black and Brown migrants.
- Partnership/Ownership/Membership – Immigration and Customs Enforcement (ICE)
Brockton Police Department Detective Gary Mercurio has been designated as a "Task Force Officer" (TFO). TFOs are local police officers granted the authority to perform the duties of federal law enforcement agencies, including making arrests of individuals sought by US Immigration and Customs Enforcement (ICE) for detention and/or deportation.
