Palo Alto: How Community Pressure Reversed Police Radio Encryption
In January 2021, Palo Alto police encrypted all radio communications without public notice or City Council involvement. Twenty months later, after sustained community advocacy led by Councilman Greer Stone, the department reversed course. Palo Alto is the most-cited US example of a successful local reversal.

The reversal means Palo Alto PD dispatch is monitorable again, and the win sits alongside CHP's open statewide model. This is the gear to actually use that access, plus the SDR and weather layer to cover everything around it.
Key Facts at a Glance
How it started
In January 2021, City Manager Ed Shikada and Police Chief Robert Jonsen encrypted Palo Alto Police Department radios without consulting City Council, posting public notice, or holding any comment period. Residents found out after the fact.
The official justification
Police leadership cited a 2020 California Department of Justice directive requiring agencies to protect personally identifiable information (PII) transmitted over radio—and said encryption was the required response.
That argument doesn't hold up
The California Highway Patrol and many other agencies follow the same DOJ directive without encrypting all communications. They comply by having officers read only partial information over the radio and using cell phones for sensitive details. Palo Alto's claim that full encryption was legally required was not accurate.
The 20-month campaign
Councilman Greer Stone led the effort to reverse the decision, keeping it on the agenda month after month when it would have been easy to let it drop.

Public comment tipped the balance
At a key City Council meeting, eight members of the public spoke. Seven supported removing encryption.
Bob Moss, Resident
"A reporter getting to a scene would help prevent excessive force by police officers because they know they're being watched."
Eric Scheie, Former Police Review Commissioner
"It's a question of having free access to information, as well as basic transparency and accountability... Secrecy in government has a bad track record."
Councilman Greer Stone
"Sometimes the road to doing the right thing can be windy and long, but I think we got it right here."
That combination—sustained council leadership and clear public support at the meeting—gave the department enough political cover to change course.
What replaced encryption: the CHP model
Palo Alto adopted the approach used by the California Highway Patrol, which handles PII protection without blocking public access:
Partial information over radio
Officers read only portions of sensitive information over the radio — enough for dispatch coordination, but not full PII.
Cell phones for sensitive details
For truly private information, officers call the dispatch center on cell phones rather than broadcasting over radio.
DOJ compliance maintained
This approach fully complies with California DOJ requirements — proving encryption was never legally necessary.
Public access preserved
The community can once again monitor police activity in real time, maintaining transparency and accountability.
"By Sept. 1, Palo Alto would follow the model of the CHP, which protects personal information by having officers read only pieces of the information over their radios."
— Acting Chief Andrew Binder, announcing the reversalWhy the campaign worked
Six factors drove the reversal:
Political champion
Councilman Greer Stone provided sustained leadership, keeping the issue on the agenda and organizing support. Every successful transparency fight needs an elected champion.
Public engagement
Seven of eight public speakers at a key meeting supported unencryption. Showing up and speaking at public meetings matters enormously.
Viable alternative
The CHP model provided a concrete alternative that addressed police concerns while preserving transparency. Offering solutions—not just opposition—strengthened the case.
State-level support
Senator Becker's SB 1000 legislation applied additional pressure, showing that the issue had statewide attention.
Leadership change
Acting Chief Andrew Binder was more receptive than his predecessor. Sometimes progress requires waiting for new leadership—or creating pressure for that change.
Persistence
Twenty months is a long time. The advocates didn't give up after initial setbacks. Sustained pressure eventually won.
What the reversal changed beyond Palo Alto
The Palo Alto case has been used as evidence in other cities' advocacy efforts:
Oakland advocates cite Palo Alto
Civil rights attorneys urging Oakland's police chief to reconsider encryption specifically pointed to Palo Alto's reversal as proof that alternatives exist.
Legislative momentum
Senator Becker's legislation drew on Palo Alto's experience, proposing that all California agencies adopt similar transparency-preserving alternatives.
National attention
Palo Alto's success has been covered by press freedom organizations and journalism groups as a model for other communities.
"This is a good example of public advocacy leading to positive change."
— Councilman Greer StoneApplying these lessons
Palo Alto demonstrates that reversals happen. Here's what translated from that campaign to a replicable approach:
Find your champion
Identify a City Council member, commissioner, or elected official who will lead the fight. Without political leadership, progress is much harder.
Show up and speak
Public comment at council meetings matters. When seven of eight speakers support transparency, it's hard for officials to ignore.
Propose the CHP model
Don't just oppose encryption—offer the CHP alternative. Show that privacy concerns can be addressed without eliminating public access.
Build a coalition
Connect with local journalists, press freedom groups, civil liberties organizations, and community watchdogs. Strength in numbers.
Be persistent
Palo Alto took 20 months. Don't expect immediate victory, but don't give up either. Sustained pressure eventually works.
Document everything
Track police claims, note when alternatives are rejected, and build a record that can be used to hold officials accountable.
