Police Encryption in Massachusetts
Boston Police encrypted all radio on August 9, 2025, just nine days before a radio blackout during an active shooting at the Dominican Festival. The city that established America's first Watch in 1631 now operates some of the most opaque police communications in the nation.
Massachusetts at a Glance
Massachusetts stands out as an early encryption adopter. While many states began encrypting after 2020, Massachusetts State Police went dark in 2014 and Boston PD followed in 2016. This head start means Bay State residents have lived without scanner access longer than most Americans.
The Greater Boston area—home to over 4.8 million people—is largely encrypted. Cambridge, the MBTA Transit Police, and Suffolk County have all followed Boston's lead. Outside the metro, results are mixed: Worcester and Springfield have partial encryption, while Cape Cod and some rural areas remain open.
Boston: August 2025 Encryption
Three Days' Notice
On August 6, 2025, Boston Police announced they would encrypt all radio communications on August 9. Three days' notice to end 394 years of public oversight. The department cited officer safety, operational security, and stopping "bad actors" from monitoring police activity.
The New England First Amendment Coalition immediately condemned the move. Justin Silverman warned it would "cut off access for real-time information about police activity" for journalists and the public who rely on scanners for neighborhood safety awareness.
The Dominican Festival Failure
Nine days after encryption, on August 17, 2025, the main police radio channel went dark for approximately 30 minutes during an active shooting at the Dominican Festival in Franklin Park. Five people were shot while officers scrambled without primary communications.
City Councilors Erin Murphy and Ed Flynn demanded an investigation. The police union flagged the "inexplicable" blackout. BPD disputed the 30-minute timeline but acknowledged officers had to switch channels. Read the full Boston case study.

Regional Analysis
Greater Boston
The Boston metro area is one of the most encrypted regions in the country. Boston PD, Cambridge, Somerville, and surrounding communities have followed the encryption trend. Transit Police coverage of the MBTA is also encrypted.
- Boston PD: Encrypted since 2016
- Cambridge PD: Encrypted
- MBTA Transit Police: Encrypted
- Suffolk County: Encrypted
Central Massachusetts
Worcester and surrounding communities have taken varied approaches. Worcester PD has partial encryption while many smaller communities maintain open communications. The region serves as a transition zone between encrypted Boston and more open Western MA.
- Worcester PD: Partial encryption
- Fitchburg: Mixed status
- Leominster: Mostly open
- Smaller towns: Generally open
Western Massachusetts
Springfield, operating under DOJ oversight following a pattern-and- practice investigation, has partial encryption. The Pioneer Valley and Berkshires have more mixed approaches, with many smaller departments remaining open.
- Springfield PD: Partial (DOJ oversight)
- Holyoke: Partial
- Northampton: Mostly open
- Berkshire County: Mixed
Cape Cod & Islands
Barnstable County and the Cape Cod region have maintained more open communications. Tourism-dependent communities value public information access, and smaller department budgets limit encryption adoption.
- Barnstable PD: Open
- Yarmouth: Open
- Martha's Vineyard: Mostly open
- Nantucket: Open
Massachusetts Encryption Timeline
Boston Marathon Bombing: Open Radio Saves Lives
Open police, fire, and EMS radio channels enable rapid multi-agency coordination during the Marathon bombing response. The after-action report praises interoperable communications that connected responders across eight cities and towns.
Smaller Cities Encrypt
Lawrence, Springfield, and Haverhill encrypt operations. Worcester and Lowell implement partial encryption. The national encryption wave following George Floyd protests accelerates trends in gateway cities.
Boston Announces Encryption with 3 Days' Notice
Boston Police announces conversion to encrypted digital radio. The New England First Amendment Coalition immediately condemns the move as a blow to transparency and public safety awareness.
Boston Goes Dark
All Boston Police communications become encrypted. A 5-minute delayed feed is offered at radio.rapidsos.com/boston, but real-time access for journalists and the public ends after 394 years.
Radio Blackout During Dominican Festival Shooting
Nine days after encryption, the main police channel goes dark for approximately 30 minutes during an active shooting at Franklin Park. Five people wounded. City councilors demand investigation.
Impact on Massachusetts Communities
Boston Journalism
The Boston Globe, Boston Herald, WCVB, and WBZ now cover Boston police incidents entirely through official channels. No independent verification of response times. Boston's experience shows what other cities can expect long-term from encryption.
Higher Education
With over 100 colleges and universities, Massachusetts has a unique campus safety dimension. Parents and students who once monitored scanners during incidents now rely entirely on institutional notifications—controlled by the institutions themselves.
Boston Marathon Legacy Lost
Open radio enabled the coordinated 2013 Marathon bombing response. Future incidents of similar magnitude will be covered entirely through official channels—the same channels that failed during the Dominican Festival shooting just 9 days after encryption.
Springfield DOJ Oversight
Springfield PD operates under DOJ oversight for civil rights violations. Yet like Minneapolis, the department maintains partial encryption—limiting the community oversight that could help verify reform compliance.
What Bay Staters Can Do
Support State Legislation
Massachusetts has strong open government traditions but no law protecting scanner access. Contact your state representative and senator on Beacon Hill to support transparency legislation for police communications.
Document Long-Term Impact
Massachusetts provides a preview of long-term encryption effects. If you've been impacted—as a journalist, community organizer, or resident—document your experience. These stories help other states understand what's at stake.
Recognize Open Communities
Cape Cod and other areas that remain open deserve recognition. Support transparency-friendly local officials and publicly acknowledge departments that maintain public access despite regional trends.
Connect with Press Freedom Groups
New England press associations and the ACLU of Massachusetts advocate for transparency. Connect with these organizations to support ongoing efforts to restore or protect scanner access where possible.
