Watching?

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

Flock told you 130.
The real number is 271,577.

What Flock's public portal shows

130

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

271,577

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.

// What We Are Asking For

Our Demands

*
End the Flock Contracts
Nevada County SO, Grass Valley PD, and Nevada City PD should terminate their contracts with Flock Safety. More than 80 communities, including Austin, Denver, Cambridge, and Santa Cruz, have already done so.
*
Explain the Stripped Records
Over 13 million searches with every reason column removed from the public records response. Flock's own portal says reasons are stored indefinitely. The public has a right to know why they were hidden.
*
Answer for the Federal Access
ATF, FBI, Postal Inspection Service, Air Force bases, NCIS, and a federal fusion center all searched Nevada County residents' plates. Under what authority? Residents deserve answers.

My name is [your name], I'm a resident of Grass Valley, and I'm here to ask the council to terminate our contract with Flock Safety.

Public records obtained through the California Public Records Act show that the Flock cameras owned by Grass Valley PD have been searched over 7.5 million times by 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).

The same data shows 1,175 searches of Grass Valley cameras by federal immigration enforcement, every one of them happening after the California Attorney General explicitly prohibited that kind of sharing in October 2023.

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 Grass Valley to be the next. Thank you.

Subject: Please terminate Grass Valley PD's contract with Flock Safety

Mayor Hodge and Council Members,

I am a resident of Grass Valley writing to ask the Council to terminate Grass Valley PD's contract with Flock Safety.

Public records obtained through the California Public Records Act show our Flock cameras have been searched over 7.5 million times by outside agencies, with more than five million of those searches coming from agencies outside California, which directly 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 explicitly prohibited that sharing in October 2023.

More than 80 communities have already ended their Flock contracts, including Santa Cruz, the first city in California to do so by a 6-1 council vote. Mountain View, South Pasadena, Cambridge, Denver, Austin, and Eugene have followed.

I am asking the Council to make Grass Valley next. The full data is at deflocknc.org.

Thank you,
[Your name]
[Your address]
