Nevada County, CA Central Sierra Foothills DSA · DeFlock Working Group
We filed public records requests and found that Flock Safety's license plate cameras, installed by Nevada County SO, Grass Valley PD, and Nevada City PD, have been searched over 20 million times by thousands of agencies across the country, including the FBI, ATF, and US military. Residents were never told.

// The Transparency Portal Lie
What Flock's public portal shows
searches in 30 days, according to the "transparency" portal Flock directs residents to. The portal also claims all reasons are stored indefinitely.
What our CPRA data actually shows
searches in the same 30-day window. And every single "reason" column was stripped from the public records response. You can't claim transparency and hide the evidence of it.

// Grass Valley PD · Contract Terminated
Grass Valley terminated its Flock contract and the cameras are down. Residents dug this out of the city's own records, brought it to council, and won, and this is what they found.
California's Attorney General issued a bulletin in October 2023 explicitly prohibiting agencies from sharing ALPR data with immigration enforcement. Our analysis of the reason field found 1,175 searches by HSI, CBP, and Border Patrol against Grass Valley cameras — all of them after that bulletin. — Cal. AG Bulletin 2023-DLE-06
// What We're Asking Grass Valley For Next
Ending the contract removed one vendor, but it did nothing to change the process that let that contract get signed without a public hearing in the first place, and it will not stop the next company that comes to this city with something worse, which is why the rule needs to be written down.
The third point is the one the Flock records make hardest to argue with, because nobody at this city ever sat down and decided to hand Nevada County's data to the ATF, to a federal fusion center, or to Border Patrol; a vendor made that call on our behalf, and the contract allowed it.
// Federal Agencies In The Data
Zero reasons disclosed. California law prohibits sharing ALPR data with non-California entities.

// What We Are Asking For
Attend a Board of Supervisors meeting. Talk to your neighbors. Share what you found here. Surveillance only works when people don't know it's happening.

Subject: Thank you for ending the Flock contract, please write the rule down
Mayor Hodge and Council Members,
Thank you for terminating Grass Valley PD's contract with Flock Safety. Residents asked, the Council listened, and that matters.
Ending one contract removes one vendor. It does not stop the next company from selling this city something worse. I am writing to ask the Council to write the rule down, in three parts.
First, pass a Community Control Over Police Surveillance (CCOPS) ordinance. No surveillance technology is acquired or deployed until the Council votes on it in a public hearing. Every system has a written use policy covering who may access the data, for what purposes, and how long it is kept. The department publishes an annual report on how each technology was actually used and every outside agency the data went to. Oakland, Berkeley, Davis, Palo Alto, San Francisco, and Santa Clara County have all adopted ordinances along these lines.
Second, ban facial recognition outright. Not a use policy, a prohibition. Face surveillance identifies people by their bodies rather than their plates and misidentifies women and people of color at measurably higher rates. San Francisco, Oakland, Berkeley, and Santa Cruz have already banned it.
Third, refuse surveillance equipment owned or controlled by a private company. If Grass Valley ever operates such a system, the city should own the hardware, the data should live on city systems, and no vendor should decide who else may search it.
The Flock records are the argument for all three. Our cameras were searched over 7.5 million times by outside agencies, with more than five million of those searches coming from agencies outside California, which violates California Civil Code § 1798.90.55(b). The records also show 1,175 searches by federal immigration enforcement (HSI, CBP, and Border Patrol), every one of them after the California Attorney General prohibited that sharing in October 2023. No one at the city chose to send that data to federal agencies. A private company did, because the contract allowed it, and it reached the public only because residents filed public records requests.
Grass Valley has already done the hard part. Please make it permanent. The full data is at deflocknc.com.

My name is [your name], I'm a resident of Grass Valley, and I want to start by thanking this council for terminating our contract with Flock Safety, because that decision took real courage and it made a real difference.
I'm here tonight to ask you to finish the job by writing the rule down, and there are three parts to that: pass a Community Control Over Police Surveillance ordinance so that no surveillance technology is acquired until this council votes on it in public, ban facial recognition outright, and refuse any system where a private company owns the equipment or holds our data.
The reason this matters is that ending the Flock contract removed one vendor, but it did not change the process that let that contract get signed in the first place; the cameras went up without a public hearing, our data was searched over 7.5 million times by outside agencies, and the only reason any of us found out was that residents filed public records requests.
Nobody at this city ever chose to hand our data to the ATF or to Border Patrol, and that is exactly the point, because a private company made that decision for us and the contract allowed it. San Francisco, Oakland, Berkeley, and Santa Cruz have already banned facial recognition, and Grass Valley has already done the hard part, so I'm asking you to make it permanent. Thank you.
My name is [your name], I'm a resident of Grass Valley, and I'm not here as a lawyer or a policy expert but as someone who lives here, drives here, and is raising [my family / my kids] here, and I want to thank this council for ending the Flock contract, because you listened to people like me and you acted.
I want to be honest about why I'm still here, though, because the thing that bothered me most was never the cameras themselves; it was that nobody asked us. There was no town hall, no ballot measure, and no public hearing where the question of whether our city should be plugged into a national surveillance network was put to the people who would actually be surveilled by it, and most of us only found out about any of it because a neighbor filed a public records request.
For a couple of years, every time I drove past one of those cameras I was photographed, and my plate, my vehicle, my route, and the time and date of my trip were logged into a private company's database, not because I was suspected of anything but simply because I drove down a public road, and that is the kind of blanket surveillance that the Fourth Amendment was written to forbid.
Some will say "if you've done nothing wrong, you have nothing to hide," and I would ask them whether they lock their front door at night or close their curtains, not because they are hiding crimes but because protecting a private life is a basic right, and it is a right that gets handed away quietly whenever a contract like this one is signed without the public in the room.
So my ask is simple, and it is really about who gets to decide. Please pass a Community Control Over Police Surveillance ordinance, so that the next time someone offers this city a surveillance system it has to come to you in public instead of arriving as a signature on a contract residents discover years later. Please ban facial recognition outright, because a camera that knows my face is a different thing from a camera that reads a plate, and I do not want to live somewhere I can be identified by name every time I walk downtown. And please refuse any system where a private company owns the equipment or holds the data, because no one at this city chose to send our records to federal agencies; a vendor did that, and the contract let it happen.
You already did the hard part by ending the contract, and I am asking you to make sure that decision holds for whoever sits in these seats next. Thank you.
My name is [your name], I'm a resident of Grass Valley, and I want to thank this council for terminating Grass Valley PD's contract with Flock Safety, because that was the right call and it was not an easy one. I'm here tonight to ask you to protect that decision by writing three rules into city law.
It is worth remembering what the records showed, because that is the case for all three. Grass Valley PD's cameras were searched over 7.5 million times by outside agencies, with more than five million of those searches coming from agencies outside California, in direct violation of California Civil Code Section 1798.90.55(b), and the agencies querying us included a federal fusion center, the Postal Inspection Service, Air Force bases, and the Naval Criminal Investigative Service.
The data also includes 1,175 searches by Homeland Security Investigations, Customs and Border Protection, and the Border Patrol, every one of them after the California Attorney General explicitly prohibited that sharing in October 2023, along with more than 54,000 searches with no valid reason given. Not one of those facts reached the public through the city; residents pieced them together from records requests they filed themselves.
The first rule is a Community Control Over Police Surveillance ordinance, which would require that the council approve any new surveillance technology in a public hearing before it is acquired or deployed, that every system have a written use policy covering who may access the data, for what purposes, and how long it is retained, and that the department publish an annual report on how each technology was actually used and who the data was shared with; none of that is novel, since Oakland, Berkeley, Davis, and San Francisco have all adopted ordinances along these lines.
The second rule is an outright ban on facial recognition, not a use policy and not a restriction, because face surveillance identifies people by their bodies rather than their license plates, it misidentifies women and people of color at measurably higher rates, and San Francisco, Oakland, Berkeley, and Santa Cruz have already decided that no set of guardrails makes it acceptable in a free city.
The third rule is that this city will not deploy surveillance equipment owned or controlled by a private company, meaning the city owns the hardware, the data lives on city systems, and no vendor decides who else may search it. That is the direct lesson of the Flock records, because no one in this room voted to send our data to the ATF or to Border Patrol; a private company did, and the contract permitted it.
So I am asking the council to direct staff to bring forward an ordinance covering all three rules, to publicly disclose the reason fields withheld from our records requests, and, now that the cameras themselves are down, to confirm on the record that the vendor's copy of everything they collected here has been deleted. Thank you.
My name is [your name], I'm a resident of Nevada County, and I'm here to ask the Board to use its budget authority to defund the Sheriff's contract with Flock Safety.
Public records obtained through the California Public Records Act show that the Flock cameras owned by the Nevada County Sheriff's Office have been searched over 13 million times by 4,654 different outside agencies, with more than five million of those searches coming from agencies outside California, which directly violates California Civil Code Section 1798.90.55(b).
Flock also publishes a "transparency portal" that the Sheriff's Office points residents to, which claims about 130 searches happen in a 30-day window, while our records covering the same window show 271,577 searches, an undercount of two thousand times.
More than 80 communities have already ended their Flock contracts, with Santa Cruz becoming the first city in California to do so, and we are asking Nevada County to be the next. Thank you.
My name is [your name], I'm a resident of Nevada County, and I'm not here as a lawyer or a policy expert but as someone who lives here, drives here, and is raising [my family / my kids] here, which is why I want to talk about what it means that the Sheriff's Flock cameras went up without ever asking the people of this county.
There was no town hall, no ballot measure, and no public hearing where the question of whether our county should be plugged into a national surveillance network was put to the people who would actually be surveilled by it; instead, the contract was signed, the cameras went up, and most of us only found out about any of it because someone filed a public records request.
The bigger issue, though, isn't even how the decision was made, but what these cameras actually do, because every time I drive past one I am photographed and my plate, my vehicle, my route, and the time and date of my trip are all logged into a private company's database, not because I am suspected of any crime but simply because I drove down a public road, and that is the literal definition of a general warrant that the Fourth Amendment was written to forbid.
Some will say "if you've done nothing wrong, you have nothing to hide," and I would ask them whether they lock their front door at night or close their curtains, not because they are hiding crimes but because protecting a private life is a basic right that license plate readers strip away from every resident, without consent, without a warrant, and without any real chance to object.
None of this is theoretical, either, because ALPR data has been used elsewhere to track domestic violence victims to safe houses, to misidentify innocent drivers in ways that have led to guns-drawn traffic stops, and here in Nevada County it has been handed over to dozens of federal and out-of-state agencies that California law specifically forbids from receiving it, all of which is to say that this technology has not made our county safer but has only made us watched.
I am asking the Board to use the authority you do have, which is your control over this office's budget, to defund the Flock contract, and to restore the basic principle that in this country the government cannot follow you everywhere unless it has a specific reason to. Thank you.
My name is [your name], I'm a resident of Nevada County, and I'm here this morning because over the past year our county has been quietly plugged into a national surveillance network operated by a private company called Flock Safety, which is something most residents have no idea happened, and I am asking this Board to look at the public records yourselves and use your budget authority to end this contract.
Since installation, the Flock cameras owned by the Nevada County Sheriff's Office have been searched over 13 million times by 4,654 different outside agencies, with more than five million of those searches coming from agencies outside California, which is a direct violation of California Civil Code Section 1798.90.55(b), the state law that prohibits sharing automated license plate reader data with any non-California entity.
The agencies in our data include over eight thousand searches by the ATF in Nashville and Louisville, hundreds of searches by the FBI, more than three thousand searches by the United States Postal Inspection Service, and queries from Langley Air Force Base, Wright-Patterson Air Force Base, the Naval Criminal Investigative Service, and the National Park Service, none of which are California agencies and none of which have any clear jurisdiction over Nevada County.
Flock also publishes what it calls a "transparency portal" that the Sheriff's Office points residents to, and that portal claims roughly 130 searches happened in a typical 30-day window, while our public records covering the exact same 30-day window show 271,577 searches, an undercount of roughly two thousand times, with every "reason" field in the released audit logs stripped before they ever reached the public.
More than 80 communities have ended their Flock contracts in the past year, including Santa Cruz, which became the first city in California to do so by a 6-to-1 council vote, Mountain View, which followed unanimously in February, and South Pasadena, Cambridge, Denver, Austin, and Eugene, all of which have walked away.
The Sheriff is independently elected and this Board cannot order her to do anything, but you control her budget, and I am asking you to do three things: defund the Flock Safety line item in the next budget cycle, pass a resolution publicly calling on the Sheriff to terminate the contract, and demand the public disclosure of every reason field and search log that was withheld from our public records requests. Thank you.
