The Marin County Sheriff’s Office is the latest California law enforcement agency to get caught sharing automated license plate reader (ALPR) data from their Flock Safety system with out-of-state and federal agencies. EFF and the ACLU of Northern California are calling them out for this direct violation of California law, which has put every driver in the county at risk and is especially dangerous for immigrants, abortion seekers, and other targets of the federal government.

Today, we sent the Marin County Sheriff’s Office (MCSO) a demand letter and request for records under the California Public Records Act following the Point Reyes Light’s recent report that MCSO provided non-California agencies access to its ALPR database. This directly violates California law and the terms of the 2022 Settlement Agreement in our case Lagleva v. Marin County Sheriff.

ALPRs are cameras that capture images of vehicles and upload their location to a searchable, shareable database. They are a mass surveillance technology that collects data indiscriminately on every vehicle on the road.

Sharing ALPR data with out-of-state or federal agencies—for any reason—violates California law (SB 34). If this data is shared for the purpose of assisting with immigration enforcement, agencies violate an additional California law (SB 54).  

But network audit logs obtained by Point Reyes Light show that during the final months of 2024, Marin County Sheriff’s Office shared ALPR data with multiple out-of-state and federal agencies, including 254,131 times in November 2024 alone. Many of these searches were conducted by law enforcement in states that impose severe restrictions on reproductive care and have a history of assisting ICE, including Alabama, Indiana, Kentucky, Florida, and Texas.

This sharing violated state law and “exposed sensitive driver location information to misuse by the federal government and by states that lack California’s robust privacy protections,” the letter explains.

This is not the first time MCSO has shared Marin County ALPR information with federal and out-of-state agencies in violation of California law.

Back in 2021, on behalf of community activists, EFF and ACLU sued the Marin County Sheriff for illegally sharing millions of local drivers’ license plate numbers and location data with hundreds of federal and out-of-state agencies, including ICE and Border Patrol.

The parties eventually reached a settlement, under which the Sheriff agreed to stop sharing license plate and location information with agencies outside of California to comply with state laws SB 34 and SB 54.

“MCSO’s November 2024 audit report shows that your office has violated not only SB 34, but the terms of the Lagleva Settlement Agreement as well,” the letter explains.

EFF and ACLU are urging MCSO to launch a thorough audit of its ALPR database, institute new protocols for compliance, and assess penalties for any employee found to be sharing ALPR information out of state.

“While your office claims that it took deliberate steps to disable nationwide data-access capabilities and ensure your system operated within strict privacy safeguards, you have not explained how outside agencies nonetheless obtained access, how you plan to prevent future violations of SB 34 and the Lagleva Settlement Agreement, or why you did not take steps to inform the public and the Marin County Inspector General once you learned about the breach,” the letter explains.

As we’ve demonstrated over and over again, many California agencies continue to ignore these laws, exposing sensitive location information to misuse and putting entire communities at risk. As federal agencies continue to carry out violent ICE raids, and many states enforce harsh, draconian restrictions on abortion, ALPR technology is already being used to target and surveil immigrants and abortion seekers. These incidents have made it clear that having ALPR programs are incompatible with the protection of residents. California agencies, including Marin County Sheriff’s Office, have an obligation to protect the rights of Californians, even when those rights are not recognized by other states or the federal government.

Access to accurate information about reproductive and maternal health can be critical. But on Meta's platforms, simply talking about prescription medication, abortion care, or one's own medical experiences can be enough to trigger content removals and account restrictions.

That's why EFF recently submitted a public comment to the Meta Oversight Board in its consideration of a case involving an Instagram post about prescription drugs during pregnancy and childbirth. The case touches upon a topic we’ve been documenting for some time; last year we collected stories from individuals who had experienced censorship of reproductive health information on various platforms. Meta in particular stood out: Its moderation systems routinely fail to distinguish between prohibited drug transactions and legitimate discussion of medications, including educational information and people's firsthand experiences with healthcare.

Through our Stop Censoring Abortion project, EFF collected nearly 100 submissions from healthcare providers, clinics, educators, advocates, researchers, and others whose reproductive health content had been removed or suppressed by social media platforms. What we found was alarming: systemic over-enforcement, confusing policies, arbitrary takedowns, sudden account bans, de-ranking, and appeals that too often went nowhere.

Talking About Medication Isn't the Same as Selling It

In almost every case we reviewed, the censored posts and accounts did not actually violate the platforms' stated rules. Meta frequently cited its Restricted Goods and Services policy, which prohibits attempts to buy, sell, trade, donate, gift, or request pharmaceutical drugs. But the content EFF documented overwhelmingly consisted of factual or educational information—not attempts to sell or distribute drugs.

The consequences were significant. For example, the Miscarriage+Abortion Hotline had its Instagram account restricted and posts removed even though it was providing information about legally obtaining medication rather than offering pharmaceuticals for sale. Red River Women's Clinic and the RISE reproductive health research center at Emory University had accounts locked after posting about mifepristone.

Other users reported having their content quietly de-ranked or “shadowbanned,” limiting its reach without giving them meaningful notice or recourse. We believe educational content and people's experiences involving reproductive healthcare and medication should not be suppressed in this way.

And when Meta gets these decisions wrong, the appeals process too often fails to fix them. In several cases EFF documented, accounts were restored only after journalists drew attention to the problem or someone with a personal connection inside Meta intervened. A moderation system shouldn't require knowing the right person to get an erroneous decision reversed.

Meta Can—and Must—Do Better

Our submission calls on Meta to make five changes—the same five changes we asked for last year.

First, Meta should publish clear, understandable policies so users can know what content is permitted and what might result in removal, downranking, or account suspension. Second, those rules must be enforced consistently and fairly. Third, Meta must provide meaningful explanations for enforcement decisions, including what rule was violated and how users can appeal. Fourth, users need a functional appeals system that doesn't depend on insider access.

Finally, Meta should expand human review. Reproductive healthcare is precisely the sort of nuanced and context-dependent subject that automated moderation systems struggle to understand. As our research shows, automated systems can mistake education for drug sales, misinterpret terminology, overlook cultural and political context, and even classify legitimate advocacy as dangerous content. Human moderators should therefore play a greater role when automated systems flag sensitive healthcare information or political expression.

Meta has chosen to allow discussion of reproductive healthcare, including abortion, on its platforms. That commitment means little if its moderation systems nevertheless prevent people from accessing or sharing that information.

At a moment when reproductive rights are under attack around the world, the stakes are particularly high. Restricting access to essential healthcare information can have profound consequences, especially for people who already face barriers to reproductive care.

Users deserve a system in which rules aren't applied arbitrarily, appeals actually work, and vital health information isn't silenced because an automated system failed to understand its context. Meta can—and must—do better.
