Fairfax County: Virginia's Largest Jurisdiction Encrypts
In March 2026, Fairfax County Police announced plans to encrypt all eight dispatch channels, following Prince William County, Arlington, and Virginia State Police, which had already gone dark
Key Facts
The Announcement
On March 10, 2026, the Fairfax County Police Department (FCPD) presented its encryption plans to the Board of Supervisors' Safety and Security Committee. The department announced it will encrypt its eight primary dispatch channels—each corresponding to one of the county's police districts—in a "slow, deliberate" phased approach.
Fairfax County is Virginia's most populous jurisdiction, with over 1.15 million residents. Prince William County encrypted on January 5, 2026. Arlington County and Virginia State Police had already gone dark before that.
"If I were a criminal and I wanted to target individuals in Fairfax County for identity theft, fraud or scams... I could just listen to the radio."— Maj. Brendan Hooke, Fairfax County Police Department
What Northern Virginia listeners can still monitor
Fairfax's eight dispatch channels going dark is a policy choice, not a technical necessity—and no gear undoes it. But the DC metro still has a dense layer of unencrypted traffic: federal agencies, aviation from Dulles and Reagan, amateur nets, NOAA weather, and adjacent Virginia and Maryland agencies that haven't (yet) encrypted.
What's Being Encrypted
Will Be Encrypted
- All 8 dispatch channels, one for each police district
- Real-time calls for service
- Suspect descriptions
- Stolen vehicle locations
- Personal information (addresses, names, SSNs)
Remaining Unencrypted
- Some "side channels" for automatic dispatch
- Informal officer coordination channels
- Specialized unit channels (already encrypted)
- "Elevated" event channels (barricades, etc.)
The department currently uses eight primary radio channels monitored by dispatchers, plus additional side channels. Some specialized channels for units like SWAT are already encrypted.
Reasons Given for Encryption
FCPD officials presented several justifications to the Board of Supervisors:
Personal Information Protection
Officers broadcast addresses, names, and even Social Security numbers during routine calls. FCPD argues this creates identity theft risks.
Criminal Exploitation
Police claim to have found suspects with scanner apps on their phones "before, during or after their crime" to evade capture.
Social Media "Harvesting"
Major Dana Ferreira cited social media accounts that harvest broadcasts "for content generation" and "clicks."
"Protecting people's personal information, especially things like social security numbers, are our best practice."— Jeffrey McKay, Board of Supervisors Chairman
What's Missing: Alternative Approaches
FCPD's presentation to the Board didn't address alternatives that other jurisdictions have used:
Training changes
Officers can be trained to avoid broadcasting SSNs and sensitive information over radio. Many departments have done this without encrypting dispatch.
Mobile data terminals
Sensitive personal information can be sent via encrypted MDTs in patrol cars rather than broadcast over air.
Delayed feed
Boston implemented a 5-minute delayed public audio feed after encrypting in August 2025, preserving some accountability while addressing real-time tactical concerns.
Media access program
San Antonio has given newsrooms encrypted radio receivers for more than 30 years without documented security problems.
Regional Context
Fairfax County's encryption is part of a broader Northern Virginia pattern. The March 2026 board presentation listed agencies that have already encrypted:
The department's presentation noted that "additional large agencies in the National Capital Region are considering moving to encryption."
Public Access Commitments
FCPD stated it will continue providing information through alternative channels:
Incident updates on department social channels
Information on major incidents via press conferences
Records available through formal requests
Crime data published online
The problem with these alternatives
Every one of these channels puts police in control of what information reaches the public and when. Real-time scanner access provided independent verification that none of them can replicate:
- Social media posts can be delayed, edited, or simply not published
- Press briefings happen after police have shaped their narrative
- FOIA requests take days or weeks
- Open data portals reflect what the department decides to share
Impact on DC Metro Area
Once Fairfax County's rollout completes, the Washington DC metro area will have virtually no publicly accessible police radio:
Journalists covering the DC area will have to rely entirely on official statements and FOIA requests. Breaking news coverage of Northern Virginia incidents will slow to the pace of press releases.
What Residents Can Do
Contact Board of Supervisors
The Board can influence implementation. Ask about media access provisions or delayed feed alternatives.
Board of Supervisors websiteAttend Committee Meetings
The Safety and Security Committee handles encryption policy. Monitor agendas and speak during public comment.
Request Alternatives
Push for Boston-style delayed feed or San Antonio-style media access as conditions of encryption.
Contact State Legislators
Virginia has no statewide encryption transparency requirements. Advocate for state-level protections.
