- Association/Collaboration – Amazon
The Wellesly Police Department participates in Amazon’s "Ring network," which as reported in The Verge, "lets law enforcement ask users for footage from their Ring security cameras to assist with investigations." The Ring is an Amazon-produced "video doorbell, which allows Ring users to see, talk to, and record people who come to their doorsteps," and which "sends notifications to a person’s phone every time the doorbell rings or motion near the door is detected."
- Partnership/Ownership/Membership – Anti-Defamation League (ADL)
In 2014, Chief of the Wellesley Police Department Terrence Cunningham participated in a “counterterrorism seminar” in Israel, as part of an all-expenses-paid delegation of US law enforcement to Israel sponsored by the New England chapter of the Anti-Defamation League (ADL). The New England Chapter of the Anti-Defamation League (ADL) sponsors annual all-expenses-paid delegations to Israel for high-ranking New England police, ICE, FBI, and other security officials, where these officials meet with Israeli military, police, and intelligence agencies, with whom they train and exchange tactics including surveillance, racial profiling, crowd control, and the containment of protests.
- Partnership/Ownership/Membership – Greater Boston Police Council
The Wellesley 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.
- Partnership/Ownership/Membership – Metropolitan Law Enforcement Council (Metro LEC)
The Wellesley Police Department is a member agency of the Metropolitan Law Enforcement Council (Metro LEC). Like other Law Enforcement Councils (LECs) in Massachusetts, Metro LEC 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 and operating largely out of public view as a semi-private organization.
