East Bay Encryption: How Two Counties Coordinated a Regional Blackout
$1.5M+ spent. Multiple setbacks. And Berkeley—the last holdout—eventually fell too.
Key Facts
The Regional Coordination
What happened in the East Bay wasn't a single city's decision—it was a coordinated regional effort spanning two counties and dozens of agencies. The East Bay Regional Communications System Authority (EBRCSA) managed the transition, spending over $1.5 million on the encryption upgrade between July 2022 and June 2024.
Affected Areas
Alameda County
Population: ~1.7 million
- Oakland Police Department
- Fremont Police Department
- Hayward Police Department
- Berkeley Police Department (last to encrypt)
- Alameda County Sheriff's Office
- Multiple smaller agencies
Contra Costa County
Population: ~1.2 million
- Richmond Police Department
- Concord Police Department
- Walnut Creek Police Department
- Contra Costa Sheriff's Office
- Multiple smaller agencies
Combined impact: Nearly 3 million residents lost access to police radio communications.
The Timeline: Technical Glitches and Delays
The encryption rollout faced multiple setbacks, with technical glitches delaying what was supposed to be a coordinated regional transition.

The Berkeley Story: Last Holdout Falls
Berkeley—a city known for progressive politics and transparency—was the last agency in Alameda County with open police radio channels. But once every surrounding agency encrypted, Berkeley faced intense pressure.
Police Chief Jen Louis's Arguments
- "We've caught burglars listening to our unencrypted channels"
- Berkeley is now "only agency in Alameda and Contra Costa counties with public police channels"
- Open channels would "concentrate criminal attention on Berkeley"
- California DOJ guidance requires protecting certain private information
Community Opposition
- Berkeley Scanner founder: "The scanner has long allowed residents, journalists and volunteer responders to stay informed in real time"
- Fire Safety Commission EMT: "Especially during critical incidents like fires, protests or citywide emergencies when accurate information can literally save lives"
- Media Alliance: "When you encrypt radios, public information becomes sort of discretionary information"
The Final Vote: 8-1
Despite community opposition, the Berkeley City Council voted overwhelmingly to encrypt. The single dissenting vote reflected concerns about transparency, but the regional pressure proved too strong.
The Cost Breakdown
Regional encryption didn't come cheap. Individual agencies spent hundreds of thousands of dollars to implement encryption on top of the EBRCSA's $1.5M+ investment.
Note: This is a partial accounting. Many agencies' individual costs remain undisclosed.
The California DOJ Argument—And Its Limits
Agencies across the region cited California DOJ guidance as justification for encryption. But this argument has significant holes.
What Agencies Claimed
A 2020 California DOJ bulletin mandated protection of Criminal Justice Information (CJI) and Personal Identifying Information (PII) during radio transmissions.
What the DOJ Actually Required
The DOJ did not require wholesale encryption. Agencies like CHP and Palo Alto comply with the same requirements without encrypting all communications—they simply don't broadcast full PII over radio.

Impact on Bay Area Journalism
The East Bay has a robust local journalism ecosystem—including The Oaklandside, Berkeleyside, and the Mercury News—that relied on scanner access for breaking news coverage.
Response Time Lost
Journalists can no longer arrive at scenes as they develop—must wait for official notification
Single-Source Reporting
Police become the only source for initial incident information
Accountability Reduced
Real-time verification of police statements no longer possible
Community Monitoring Ended
Organizations like Copwatch can no longer respond to incidents in progress
Alternatives That Weren't Tried
The CHP and Palo Alto demonstrate that DOJ compliance doesn't require full encryption. The East Bay chose the most restrictive approach without adequately considering alternatives.
The CHP Model
Officers read only partial information over radio; full details transmitted via cell phone or encrypted tactical channels.
Available but not adoptedDelayed Public Access
Baltimore model: 15-minute delay on public scanner access maintains transparency while preventing real-time exploitation.
Available but not adoptedPress Credentialing
San Antonio model: Credentialed media receive access to communications with certain channels disabled.
Available but not adoptedSplit Encryption (Seattle Model)
Dispatch channels remain open; only tactical channels encrypted.
Available but not adoptedThe Domino Effect
Berkeley's fall illustrates a troubling pattern: once enough agencies in a region encrypt, remaining holdouts face enormous pressure to join. The "only open agency" argument becomes self-fulfilling.
Why This Matters for Your Region
- Regional coordination accelerates encryption — Once agencies coordinate, individual resistance becomes harder
- The "criminal attention" argument compounds — Each agency that encrypts makes it easier for the next to claim criminals will target open channels
- Advocacy must be regional — Fighting city-by-city after a regional rollout is nearly impossible
- Prevention is easier than reversal — Acting before encryption happens is far more effective than trying to undo it
What Happens Next
With the East Bay now fully encrypted, transparency advocates face an uphill battle. But the fight isn't over.
