=====Vehicle Fingerprint technology=====
While marketed as an automatic license plate reader (ALPR) system,<ref>{{Cite web|url=https://www.flocksafety.com/products/license-plate-readers|title=License Plate Readers|work=Flock Safety|access-date=2025-08-23|archive-url=https://archive.ph/D9JGD|archive-date=2025-08-23|url-status=live}}</ref> Flock's cameras capture comprehensive vehicle and occupant data beyond license plates. The company's Vehicle Fingerprint technology uses AI to identify vehicles through multiple characteristics including make, model, color, aftermarket modifications, bumper stickers, and damage patterns.<ref>{{Cite web|url=https://www.flocksafety.com/resources/how-vehicle-fingerprint-technology-works|title=How Vehicle Fingerprint Technology Works|work=Flock Safety|date=2023|access-date=2025-08-23}}</ref>
These are often referred to as license plate cameras, which creates a fundamental misunderstanding of the product's capabilities.


While marketed as ''"License Plate Readers,"'' Flock's cameras use what the company calls "''Vehicle Fingerprint"'' technology that tracks vehicles using characteristics beyond just license plates. According to Flock's own marketing materials, the system can identify vehicles even when license plates cannot be captured, advertised as turning ''"images into actionable evidence — no plate required."''<ref>{{Cite web |title=LPR Cameras |url=https://www.flocksafety.com/products/lpr-cameras |access-date=2025-08-23 |work=Flock Safety}}</ref>
Internal documentation reveals the system can detect and search for specific objects inside vehicles, including pets, packages, and the number of occupants.<ref>{{Cite web|url=https://www.404media.co/flock-safety-can-now-capture-faces-of-vehicle-occupants/|title=License Plate Surveillance Company Can Now Capture Images of Vehicle Occupants' Faces|work=404 Media|date=2024-05-16|access-date=2025-08-23}}</ref> Law enforcement can search for vehicles based on partial information such as "sedan with Christmas tree on roof" or "truck with ladder rack."<ref>{{Cite web|url=https://www.flocksafety.com/newsroom/transforming-flock-beyond-license-plate-reading-to-deliver-greater-insights-for-solving-crime/|title=Transforming Flock: Beyond License Plate Reading to Deliver Greater Insights for Solving Crime|work=Flock Safety|date=2023-10-16|access-date=2025-08-23}}</ref>

The system catalogs vehicles based on numerous distinguishing features including make, model, color, bumper stickers, dents, damage patterns, roof racks, aftermarket modifications such as wheels or spoilers, window stickers, and even mismatching paint colors.<ref>{{Cite web |last=Harwell |first=Drew |date=2021-10-22 |title=Flock license plate readers spark controversy in Golden, Colo. |url=https://www.washingtonpost.com/technology/2021/10/22/crime-suburbs-license-plate-readers/ |access-date=2025-08-23 |work=The Washington Post}}</ref><ref>{{Cite web |title=Flock Safety ALPR |url=https://www.campbellca.gov/1260/Flock-Safety-ALPR |access-date=2025-08-23 |work=City of Campbell}}</ref> Flock claims this capability is ''"unique among ALPR systems"'' & allows law enforcement to search for vehicles based on these characteristics even without a visible license plate.


This technology changes the nature of the surveillance from license plate reading to comprehensive vehicle tracking. A person could still be tracked by the unique combination of their vehicle's physical characteristics. The Electronic Frontier Foundation warns that these ''"vehicle fingerprints"'' could flag vehicles based on political bumper stickers, revealing ''"information on the political or social views of the driver,"'' or economic indicators like rust or damage, potentially "endangering anyone who might not feel the need (or have the income required) to keep their car in perfect shape."<ref>{{Cite web |date=2020-09-14 |title=Things to Know Before Your Neighborhood Installs an Automated License Plate Reader |url=https://www.eff.org/deeplinks/2020/09/flock-license-plate-reader-homeowners-association-safe-problems |access-date=2025-08-23 |work=Electronic Frontier Foundation}}</ref>
==Patent for person identification by race and physical characteristics==


Privacy advocates note that this expanded tracking capability makes the term ''"license plate reader"'' misleading, as Flock systems create detailed vehicle profiles that persist even without readable plates. It turns any distinguishing feature of a vehicle into a tracking identifier.<ref>{{Cite web |title=Stop Flock |url=https://www.stopflock.com/ |access-date=2025-08-23 |work=Stop Flock}}</ref>
A U.S. Patent granted to Flock Group Inc. in August 2022 reveals the company has developed & patented technology to identify & classify people based on race, gender, & other physical characteristics.<ref name="patent11416545">{{cite web|url=https://patentimages.storage.googleapis.com/77/9a/03/7b3b26499077d4/US11416545.pdf|title=System and Method for Object Based Query of Video Content Captured by a Dynamic Surveillance Network|website=United States Patent and Trademark Office|date=2022-08-16|access-date=2025-01-21|format=PDF|inventor=Garrett Langley; Matt Feury|patent=US11416545B1}}</ref> Patent US 11,416,545 B1 describes a system that goes beyond vehicle identification to analyze human subjects captured in surveillance footage.


==Constitutional and legal challenges==
According to the patent documentation, when the system identifies a human being in captured footage, it uses neural network modules specifically configured to classify people by "male, female, race, etc." The patent further describes using additional neural networks to identify clothing types, estimate height & weight, & other physical characteristics of individuals.<ref name="patent11416545" /> The system can then store this classification data in searchable databases, allowing law enforcement to query for people based on these physical attributes.


===Norfolk federal lawsuit===
The patent shows that Flock's technology is designed to create comprehensive profiles that can track individuals across multiple camera locations by matching physical characteristics. While Flock publicly markets its products as ''"license plate readers"'' focused on vehicles, this patent demonstrates the company has developed capabilities for detailed human surveillance & classification by protected characteristics including race and gender.<ref name="patent11416545" />
In February 2025, Chief Judge Mark S. Davis of the U.S. District Court for the Eastern District of Virginia denied Norfolk's motion to dismiss a landmark Fourth Amendment lawsuit. The case involves two residents whose vehicles were tracked 526 times in 4.5 months and 849 times over the same period, figures revealed in a September 2025 court filing.<ref>{{Cite web|url=https://www.nbcnews.com/tech/security/virginia-police-used-flock-cameras-track-driver-safety-lawsuit-surveil-rcna230399|title=Virginia police used Flock cameras to track driver 526 times in 4 months, lawsuit says|work=NBC News|date=2025-09-18|access-date=2025-08-23}}</ref> Norfolk installed 172 Flock Safety cameras in 2023 at a cost of $430,000-$516,000 annually. Police Chief Mark Talbot stated the goal was making it ''"difficult to drive anywhere of any distance without running into a camera somewhere."''<ref name="norfolk" />


Judge Davis's ruling relied on ''Carpenter v. United States'', the 2018 Supreme Court decision requiring warrants for historical cell phone location data. The court found Norfolk's ALPR network "notably similar" to the surveillance the Supreme Court deemed unconstitutional. However, courts remain divided. In November 2024, Senior U.S. District Judge Robert E. Payne in the same district denied a motion to suppress Flock evidence, holding that three vehicle snapshots don't constitute "persistent surveillance" requiring a warrant.<ref>{{cite web|url=https://valawyersweekly.com/2024/11/11/mosaic-theory-rejected-flock-camera-evidence-does-not-violate-fourth-amendment/|title='Mosaic theory' rejected: Flock camera evidence does not violate Fourth Amendment|website=Virginia Lawyers Weekly|date=2024-11-11|access-date=2025-10-05}}</ref>
Privacy advocates have raised concerns that this technology could enable discriminatory policing practices &racial profiling at scale. The ability to search for people by race or other physical characteristics across a network of thousands of cameras is a large expansion of surveillance capabilities beyond what is typically disclosed in Flock's public marketing materials.<ref>{{Cite web|url=https://www.eff.org/deeplinks/2024/04/atlas-surveillance-flock-safety|title=Atlas of Surveillance: Flock Safety|work=Electronic Frontier Foundation|date=2024-04-15|access-date=2025-01-21}}</ref>


Virginia state courts show similar disagreement. Norfolk Circuit Court Judge Jamilah LeCruise granted a suppression motion in May 2024, finding that the breadth of Flock cameras covering Norfolk requires a warrant.<ref>{{cite web|url=https://www.govtech.com/public-safety/virginia-judge-rejects-alpr-evidence-without-warrant|title=Virginia Judge Rejects ALPR Evidence Without Warrant|website=Government Technology|date=2024-05-15|access-date=2025-10-05}}</ref> Yet three other Norfolk circuit court judges denied similar motions in 2024.
==Legal challenges==


===State regulatory landscape===
===Constitutional challenges===
Only 16 states have enacted any form of ALPR regulation as of 2024 according to University of Michigan research.<ref>{{cite web|url=https://stpp.fordschool.umich.edu/news/2023/automated-license-plate-readers-widely-used-subject-abuse|title=Automated License Plate Readers widely used, subject to abuse|website=University of Michigan|date=2023|access-date=2025-10-05}}</ref> Virginia enacted House Bill 2724 in 2025 creating annual reporting requirements.<ref>{{cite web|url=https://vscc.virginia.gov/Annual%20Reports/2024%20VSCC%20Annual%20Report%20-Law%20Enforcement%20Use%20of%20ALPR.pdf|title=2024 VSCC Annual Report - Law Enforcement Use of ALPR|website=Virginia State Crime Commission|date=2024|access-date=2025-10-05}}</ref> Illinois Public Act 103-0540 explicitly prohibits use for reproductive healthcare punishment and immigration investigations.<ref>{{cite web|url=https://www.ilga.gov/legislation/publicacts/103/103-0540.htm|title=Public Act 103-0540|website=Illinois General Assembly|date=2024|access-date=2025-10-05}}</ref>
Multiple lawsuits challenge Flock's warrantless surveillance as violating Fourth Amendment protections. In ''Leaders of a Beautiful Struggle v. Baltimore Police Department'', the Fourth Circuit Court of Appeals ruled that persistent aerial surveillance violated reasonable expectations of privacy.<ref>{{Cite web|url=https://www.eff.org/cases/leaders-beautiful-struggle-v-baltimore-police-department|title=Leaders of a Beautiful Struggle v. Baltimore Police Department|work=Electronic Frontier Foundation|access-date=2025-08-23}}</ref> Legal experts argue this precedent applies to Flock's ground-based network creating similar comprehensive tracking capabilities.<ref>{{Cite web|url=https://www.law.georgetown.edu/american-criminal-law-review/wp-content/uploads/sites/15/2023/01/60-1-Carpenter-and-the-Evolving-Fourth-Amendment.pdf|title=Carpenter and the Evolving Fourth Amendment|work=Georgetown Law|date=2023|access-date=2025-08-23}}</ref>


==Other surveillance products==
Norfolk, Virginia residents filed suit in 2023 arguing the city's 172 Flock cameras constitute mass surveillance without probable cause. The lawsuit cites ''Carpenter v. United States'', where the Supreme Court ruled that persistent location tracking requires a warrant.<ref name="norfolk" /> A federal judge allowed the case to proceed, rejecting the city's motion to dismiss.<ref>{{Cite web|url=https://www.courtlistener.com/docket/67689711/leaders-of-a-beautiful-struggle-v-baltimore-police-department/|title=Leaders of a Beautiful Struggle v.

=====Flock Aerodome "Drone as First Responder"=====
===State legislation===
Flock Safety also offers an all-in-one drone product which integrates into the Flock AI Surveillance Network as well as  local law enforcement's Computer Aided Dispatch software.  The Drones are outfitted with live video cameras, thermal imaging, night vision, and potentially other sensors, and are capable of self-launching and self-navigating.<sup>[https://www.flocksafety.com/products/flock-aerodome]</sup> Flock Safety cites following potential use-cases: <blockquote>Drones are stationed across your service area, ready to respond instantly... Deploy from the dock to geo-coordinates of 911 calls, LPR hits, gunshot detection, or manually by the operator... Control multiple drones and docks with a single operator, providing continuous air support for the entire city.</blockquote>Rahul Sidhu, VP of Aviation at Flock Safety, works directly with FAA officials and actively lobbies Congress to gain favorable legislation which seeks to expand Flock Safety's surveillance network and further diminish citizen privacy.

Several states have enacted restrictions on ALPR use. Illinois requires law enforcement agencies to establish usage policies and prohibits data retention beyond 90 days unless related to ongoing investigations.<ref>{{Cite web|url=https://www.ilga.gov/legislation/ilcs/ilcs3.asp?ActID=3541&ChapterID=53|title=Illinois Compiled Statutes - Freedom from Drone Surveillance Act|work=Illinois General Assembly|access-date=2025-08-23}}</ref> New Hampshire banned ALPR use entirely except for specific toll collection purposes.<ref>{{Cite web|url=http://www.gencourt.state.nh.us/rsa/html/XXI/236/236-130.htm|title=RSA 236:130 Automated License Plate Recognition|work=New Hampshire General Court|access-date=2025-08-23}}</ref>

====Illinois audit findings (2024-2025)====
===Immigration enforcement controversy===
Illinois Secretary of State Alexi Giannoulias announced in late August 2024 that Flock Safety violated state law by allowing U.S. Customs and Border Protection to access Illinois license plate data for immigration enforcement.<ref>{{cite web|url=https://www.flocksafety.com/blog/flock-safetys-response-to-illinois-lpr-data-use-and-out-of-state-sharing-concerns|title=Flock Safety's Response to Illinois LPR Data Use and Out-of-State Sharing Concerns|website=Flock Safety|date=2024-08-25|access-date=2025-10-05}}</ref> The audit of 12 local law enforcement agencies revealed unauthorized pilot programs with CBP and Homeland Security Investigations, violating Illinois law prohibiting data sharing for immigration enforcement, gender-affirming care investigations, and abortion-related matters. Following the audit, 47 out-of-state agencies were removed from access to Illinois data.<ref>{{cite web|url=https://www.govtech.com/biz/flock-pledges-changes-after-illinois-data-sharing-accusation|title=Flock Pledges Changes After Illinois Data-Sharing Accusation|website=Government Technology|date=2024-08-15|access-date=2025-10-05}}</ref>

===Abortion and reproductive healthcare tracking===
In May 2025, Johnson County, Texas sheriff's deputies used Flock's network to track a woman suspected of self-managing an abortion. They conducted searches across 83,000+ Flock cameras nationwide with the explicit reason: "had an abortion, search for female." The search accessed cameras across multiple states including those where abortion is legal. The incident led Illinois officials to investigate and subsequently block 47+ out-of-state agencies from accessing Illinois ALPR data.<ref>{{Cite web|url=https://www.dallasnews.com/news/texas/2025/06/13/after-finding-fetal-remains-north-texas-cops-used-camera-network-to-search-for-woman/|title=After finding fetal remains, North Texas cops used camera network to search for woman|work=The Dallas Morning News|date=2025-06-13|access-date=2025-08-23}}</ref><ref>{{cite web|url=https://www.eff.org/deeplinks/2025/05/she-got-abortion-so-texas-cop-used-83000-cameras-track-her-down|title=She Got an Abortion.

====='''In Evanston:'''=====
Flock was ordered to remove 18 stationary cameras. The city put the contract with Flock on a 30-day termination notice on August 26. Flock Initially appeared to comply, removing 15 of the cameras by September 8. Later, <u>Flock was caught reinstalling all of them by the following Tuesday without authorization from the city.</u>
 
The city of Evanston responded with a cease-and-desist order for Flock to remove the new and unauthorized camera equipment.
 
Because Flock reinstalled the cameras without permission, <u>Evanston was forced to cover the cameras with tape and bags to block them from potentially logging vehicle data.</u>
 
This situation is particularly absurd, as the city was left with little choice but to physically shield the cameras due to Flock’s unauthorized action, and outright noncompliance with the wishes of the city.
 
Flock appears apprehensive to comply and remove the hardware, with a representative of flock stating:
 
“We continue to be optimistic that we will have the opportunity to have a constructive dialogue to address the City’s concerns and resume our successful partnership making Evanston safer”
 
While it is clear that flock wishes to continue their contract, this does not address the wishes of the city. In this regard, A Flock spokesperson stated: “the cameras are not active and will be uninstalled”
 
This raises concerns, as <u>it is unclear why flock chose to incur costs to install</u> <u>unauthorized inactive cameras after the initial request for removal.</u> Additionally, it is not possible, or remains extremely difficult and costly for the city to independently verify that the ‘inactive’ cameras are truly disabled.
 
It remains unclear if there is concrete financial incentive for flock to partake in these possibly illegal or otherwise unethical actions.
 
More physical cameras are ostensibly capable of creating more data, which is collected in aggregate by flock, and selectively shared with other clients. Additional data could create a clear value proposition for certain flock services, and thus effects the desirability of the services provided by flock, and potentially, the price which flock can expect to charge for their services.<ref>{{Cite web |last=Harrison |first=Alex |date=September 25th, 2025 |title=City covers Flock cameras while waiting for removal |url=https://evanstonroundtable.com/2025/09/25/city-covers-up-flock-cameras-while-waiting-for-removal/ |url-status=live |archive-url=https://archive.ph/PD1qe |archive-date=2025-10-10 |access-date=2025-10-10 |website=Evanston Roundtable}}</ref>

===Sedona termination===
Sedona, Arizona became the first Arizona city to completely terminate its Flock Safety contract in September 2025 after citizen backlash. The city had installed 11 cameras in June 2025 without prior public notice at a cost of $51,146 for the first year. The council voted 5-1 to pause the program, then unanimously 7-0 on September 9 to permanently terminate after Flock CEO Garrett Langley admitted the company had been sharing data with federal agencies. Vice Mayor Holli Ploog called Flock "not an honorable company" for the conflicting data-sharing claims.<ref>{{cite web|url=https://westvalleyfamilies.substack.com/p/sedona-pulls-the-plug-on-flock-safety|title=Sedona Pulls the Plug on Flock Safety|website=West Valley Families|date=2025-09-10|access-date=2025-10-05}}</ref><ref>{{cite web|url=https://www.knau.org/knau-and-arizona-news/2025-09-11/sedona-council-permanently-ends-license-plate-camera-program|title=Sedona council permanently ends license plate camera program|website=KNAU|date=2025-09-11|access-date=2025-10-05}}</ref>

Official Website https://www.flocksafety.com/products/license-plate-readers

Flock License Plate Readers (previously known as Flock Safety Falcon[1]), are a network of AI-powered surveillance cameras that record vehicle data for law enforcement agencies. The system operates in over 5,000 communities across 49 U.S. states.[2] According to the company's own marketing materials, Flock performs over 20 billion vehicle scans monthly.[3]

Consumer impact summary

Freedom

Residents and taxpayers have no mechanism to opt out of Flock Safety's surveillance network. The cameras operate 24/7 in public spaces, recording all passing vehicles regardless of consent. They are also placed on private premises like universities, hospitals, businesses, and neighborhood associations, which often share this data with law enforcement.[4] This data can later be integrated into predictive police platforms like Palantir.[5]

Unlike traditional security cameras that may be avoided by choosing different routes, Flock's expanding network of over 40,000 cameras makes avoidance increasingly difficult.[6] The system uses AI to create "Vehicle Fingerprints" that identify vehicles by characteristics beyond license plates, including make, model, color, aftermarket parts, window stickers, and roof racks.[7]

Privacy

While Flock Safety claims their system doesn't violate Fourth Amendment rights because "license plates are not personal information,"[8] federal courts have challenged this interpretation. In February 2024, a federal judge ruled that a lawsuit challenging Norfolk, Virginia's use of 172 Flock cameras could proceed, finding that plaintiffs had plausibly alleged the system creates a "detailed chronicle of a person's physical presence compiled every day."[9]

Data collected includes location history that can reveal sensitive information about medical visits, religious attendance, political activities, and personal associations. While Flock states data is deleted after 30 days, contracts grant them "perpetual, worldwide, royalty-free license" to use anonymized data indefinitely.[10] The system shares data across a network of over 4,800 law enforcement agencies nationally.[11]

"Anonymized Data"

While Flock's Terms and Conditions define "Anonymized Data" as customer data that is "permanently stripped of identifying details and any potential personally identifiable information" and is rendered so that a person or entity "can no longer be identified directly or indirectly," this definition includes information such as vehicle make, model, color, location patterns, and other non–license-plate attributes.[12]

Privacy researchers caution that mobility datasets labeled as "anonymized" can still be re-identified. A 2013 MIT study found that just four spatio-temporal points uniquely identified 95% of individuals in an anonymized location dataset.[13] Multiple peer-reviewed studies from 2018-2024 demonstrate that "anonymized" vehicle location data can be re-identified with high accuracy. A 2022 study showed researchers could re-identify drivers from raw vehicle network data with 97% accuracy by exploiting interdependencies in sensor measurements.[14] Research published in the Journal of Computer Science and Technology (2022) found that even 3-4 location points can uniquely identify individuals.[15]

Business model

Flock operates on a subscription model charging municipalities and law enforcement agencies $2,500 per camera annually plus installation costs.[16] Private businesses including Home Depot, Lowe's, and FedEx also deploy cameras, sharing data with law enforcement.[17][4] Contracts include automatic renewal clauses and limit municipal oversight capabilities, with cities unable to audit system operations or control how other agencies use shared data.[18]

Market control

Flock Safety has rapidly expanded to become a dominant force in automated license plate recognition, operating in 49 states with over 40,000 cameras deployed. The company's network effect creates pressure for additional jurisdictions to join, as law enforcement effectiveness depends on network coverage. Several states have begun restricting access following privacy violations, with California, Illinois, and New York limiting data sharing after immigration and abortion-related tracking incidents.[19]

Premise of a "license plate camera"

While marketed as an automatic license plate reader (ALPR) system,[20] Flock's cameras capture comprehensive vehicle and occupant data beyond license plates. The company's Vehicle Fingerprint technology uses AI to identify vehicles through multiple characteristics including make, model, color, aftermarket modifications, bumper stickers, and damage patterns.[21]

Internal documentation reveals the system can detect and search for specific objects inside vehicles, including pets, packages, and the number of occupants.[22] Law enforcement can search for vehicles based on partial information such as "sedan with Christmas tree on roof" or "truck with ladder rack."[23]

Patent for person identification by race and physical characteristics

A U.S. Patent granted to Flock Group Inc. in August 2022 reveals the company has developed & patented technology to identify & classify people based on race, gender, & other physical characteristics.[24] Patent US 11,416,545 B1 describes a system that goes beyond vehicle identification to analyze human subjects captured in surveillance footage.

According to the patent documentation, when the system identifies a human being in captured footage, it uses neural network modules specifically configured to classify people by "male, female, race, etc." The patent further describes using additional neural networks to identify clothing types, estimate height & weight, & other physical characteristics of individuals.[24] The system can then store this classification data in searchable databases, allowing law enforcement to query for people based on these physical attributes.

The patent shows that Flock's technology is designed to create comprehensive profiles that can track individuals across multiple camera locations by matching physical characteristics. While Flock publicly markets its products as "license plate readers" focused on vehicles, this patent demonstrates the company has developed capabilities for detailed human surveillance & classification by protected characteristics including race and gender.[24]

Privacy advocates have raised concerns that this technology could enable discriminatory policing practices &racial profiling at scale. The ability to search for people by race or other physical characteristics across a network of thousands of cameras is a large expansion of surveillance capabilities beyond what is typically disclosed in Flock's public marketing materials.[25]

Constitutional challenges

Multiple lawsuits challenge Flock's warrantless surveillance as violating Fourth Amendment protections. In Leaders of a Beautiful Struggle v. Baltimore Police Department, the Fourth Circuit Court of Appeals ruled that persistent aerial surveillance violated reasonable expectations of privacy.[26] Legal experts argue this precedent applies to Flock's ground-based network creating similar comprehensive tracking capabilities.[27]

Norfolk, Virginia residents filed suit in 2023 arguing the city's 172 Flock cameras constitute mass surveillance without probable cause. The lawsuit cites Carpenter v. United States, where the Supreme Court ruled that persistent location tracking requires a warrant.[9] A federal judge allowed the case to proceed, rejecting the city's motion to dismiss.[28]

State legislation

Several states have enacted restrictions on ALPR use. Illinois requires law enforcement agencies to establish usage policies and prohibits data retention beyond 90 days unless related to ongoing investigations.[29] New Hampshire banned ALPR use entirely except for specific toll collection purposes.[30]

California's SB 34 requires law enforcement to establish privacy policies, conduct annual audits, and delete non-hit data within 60 days.[31] However, enforcement remains inconsistent, with a 2020 state audit finding widespread non-compliance.[32]

Notable incidents

Immigration enforcement controversy

Internal emails obtained through FOIA requests revealed Flock provided Immigration and Customs Enforcement (ICE) real-time access to track vehicles across sanctuary cities, contradicting public statements about limiting federal agency access.[33] Following public outcry, Flock restricted ICE access in California, Illinois, and several other states, though access continues in most jurisdictions.[34]

Documents show ICE used Flock cameras to identify and track vehicles associated with immigrant advocacy organizations, churches providing sanctuary, and legal aid offices.[35] In one case, ICE tracked a vehicle from a church in Oakland to a residential address, leading to an enforcement action.[36]

Abortion access surveillance

After Roe v. Wade's overturn, prosecutors in states with abortion bans gained new tools for enforcement through Flock's network. Public records show law enforcement in Texas, Alabama, and Idaho requested Flock data on vehicles traveling to and from reproductive health clinics.[37]

Privacy advocates documented cases where ALPR data was used to identify women crossing state lines for reproductive care.[38] In response, some states enacted "shield laws" prohibiting the use of ALPR data for abortion-related prosecutions.[39]

Data breaches and misuse

A 2024 investigation revealed Flock employees accessed customer data without authorization, including running searches on romantic partners, neighbors, and journalists.[40] Internal audits found over 200 instances of inappropriate access between 2022-2024, though Flock claims to have implemented additional access controls.[41]

Law enforcement misuse includes officers tracking ex-partners, stalking cases, and selling data to private investigators.[42] A Detroit officer was terminated after using Flock to track his ex-wife's movements for six months.[43]

Security vulnerabilities

Flock Safety self-disclosed critical vulnerabilities in Q2 2025 and submitted them to MITRE for inclusion in the National Vulnerability Database.[44] Vulnerabilities in similar ALPR systems have included hardcoded passwords and unencrypted data storage.[45]

This marks the third major ALPR security disclosure in a decade. In 2015, EFF investigators found over 100 ALPR cameras unsecured on the internet. The most serious documented breach occurred in 2019 when a cyberattack compromised Perceptics, LLC, a CBP subcontractor, exposing 105,000 license plate images and 184,000 traveler facial images.[46]

Government accountability and oversight

State audit findings

California State Auditor's February 2020 investigation found Los Angeles Police Department, with a 320 million image database, had no ALPR-specific policy at all. The audit found 96% of agencies claim to have policies, but most are incomplete. Data retention periods varied wildly with no justification. LAPD maintained a minimum five-year retention period, yet couldn't demonstrate that images stored for years had investigative value. The audit found that 99.9% of the 320 million images Los Angeles stores are for vehicles that were not on a hot list when the image was made.[47]

New Jersey provides a contrasting model with mandatory annual audits of all 523 law enforcement agencies. The 2024 audit reported only two significant violations, both involving users who hadn't completed required training.[48]

A Government Technology analysis found that agencies often fail to audit ALPR systems regularly, leaving them "open to abuse by neglecting to institute sufficient oversight."[49]

Cost-benefit analysis

Arizona Department of Transportation's 2008 study of generic ALPR technology (predating Flock Safety by nine years) estimated $9.98 million for a hypothetical statewide ALPR system. The projected benefit-to-cost ratio of 9.6:1 came entirely from registration and insurance compliance, not crime reduction.[50]

Colorado's Office of Research and Statistics reported that while ALPR systems are expanding, independent academic research contradicts vendor claims. A 2011 George Mason University study concluded ALPRs "do not achieve a prevention or deterrent effect" on crime.[51]

Oakland Police Department reported 182 arrests from ALPR in the first year, representing 1.4% of homicides, robberies, burglaries, and firearm assaults. The Northern California Regional Intelligence Center states approximately 1-2 vehicles out of 1,000 initiate alerts—a hit rate of just 0.1-0.2%.[52]

Cease and desist to Deflock.me

DeFlock.me is a website allowing users to log and view the locations of ALPRs, such as Flock products. On January 30th, 2025, Flock sent a cease and desist notice to the owner of DeFlock demanding the name of the website be changed to exclude the company's brand name. The letter also stated that "the Website also implies that various license plate readers are vulnerable to security hacks. . ." which Flock alleged ". . . provides a false impression about the security of Flock Products."
