Officer Michael Tiso has been reinstated by the Revere Police Department after an internal investigation found he accessed Flock cameras and a state license-plate database more than a dozen times to monitor an ex-partner; he denies the allegations. Revere suspended him without pay for violating department policies and has since added updated policies, audit features and software alerts to prevent misuse. Records show two prior suspensions in 2020, and a separate court order in September 2026 requires the Massachusetts State Police to disclose Flock usage records after an ACLU suit.

Officer Michael Tiso of the Revere Police Department in Massachusetts has returned to duty after an internal investigation into allegations that he used Flock surveillance cameras and a state license-plate database to monitor a former partner.
Investigation And Findings
According to local reporting, the department opened an internal inquiry after receiving a complaint in December 2025. The review, reported by The Boston Globe and Boston.com, found that Tiso had accessed the Flock system more than a dozen times and queried a state license-plate database in ways the department considered problematic. Tiso denies the allegations.
Disciplinary Action And Reinstatement
Revere suspended Tiso without pay, saying he "violated department policies and use protocols." Following the internal review and discipline, the department has reinstated the officer.
Policy Changes And Technical Safeguards
Revere announced it will continue using Flock Safety cameras but has implemented stricter controls to curb misuse. Measures include updated departmental policies, enhanced audit features to track and review searches, and software upgrades intended to trigger alerts for unusual query activity and strengthen audit trails.
Context And Background
The woman who filed the complaint said she and Tiso dated from March 2021 through October 2022 and later alleged he monitored her and family members via the camera network. The two have exchanged multiple complaints over recent years; some were later withdrawn. Public records from the Massachusetts POST Commission show Tiso had two prior suspensions in 2020 for unrelated matters.
Revere Police Chief Maria LaVita said the department must "ensure that each and every search is connected to a legitimate, lawful purpose and that searches comply with department policy and all applicable laws."
Wider Developments
While Revere intends to keep its Flock Safety system, other Massachusetts municipalities have chosen to cancel contracts with the company. Separately, reporting by 10 WJAR notes that in September 2026 a judge ordered the Massachusetts State Police to disclose records about their use of Flock cameras following a lawsuit filed by the ACLU of Massachusetts.
