YouTuber Says Cops Visited Him After He Built a Flock-Style Camera to Track Cops

📝 Discussion Summary (Click to expand)

1. Power imbalance – police enjoy special privileges the public does not

“Well I mean the state does have the monopoly on violence.” – hypfer
“police are able to do many things that the general public aren't allowed to do, in order to do their jobs.” – joemi

2. Flock’s legality rests on the claim there is no reasonable expectation of privacy in public

“Most of those caveats are about spaces that aren't actually public… there's not much in the way of restrictions, and nothing where police have special privileges.” – wat10000
“Isn't Flock's alleged legality predicated on the principle that there is no 'reasonable expectation of privacy' in public?” – caconym_

3. Police frequently misuse Flock data (stalking ex‑partners, harassment) with little oversight

“There's a list of 81 known instances of police stalking romantic interests, sometimes querying Flock hundreds of times… Some of the cases involve sexual assault and kidnapping as well.” – redwall_hp
“Police officers can stalk their exes over 2000 times…” – ajsnigrutin

4. Calls to ban Flock or impose symmetric surveillance (“watch the watchers”)

“The clear solution is to ban it, but our Government has both a financial and power stake in keeping people surveilled…” – ToucanLoucan
“I don't want HN'ers setting up surveillance networks… So this post, bringing attention to that issue, is good, imo.” – ImPostingOnHN


🚀 Project Ideas

OpenFlock Public ALPR Network

Summary

  • A decentralized, open‑source network of low‑cost license‑plate readers that lets citizens upload and query plate sightings to monitor police and government vehicle movements in real time.
  • Core value proposition: Puts surveillance capabilities in the hands of the public, mirroring what law enforcement enjoys and increasing accountability.

Details

Key Value
Target Audience Privacy activists, journalists, concerned citizens, community watch groups
Core Feature Crowdsourced ALPR data ingestion, real‑time map of sightings, searchable plate history, API for third‑party tools
Tech Stack Raspberry Pi + OpenALPR camera, Python/FastAPI backend, PostgreSQL/PostGIS, React/Leaflet frontend, Docker deployment
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters noted the obvious next step: “The obvious next step, otherwise, is for someone to start OpenALPRMap and we all get to suffer together.” – rootusrootus
  • The idea mirrors the sentiment that “putting a tracker on every cop's car and giving the public access to it” would restore balance – shortstuffsushi
  • Potential for discussion: invites debate on sousveillance vs surveillance, practical utility in documenting police patrols or identifying misuse of ALPR data.

FlockWatch: Personal Data Access & Deletion Portal

Summary

  • A web service that guides individuals through submitting data‑subject access requests to Flock (and similar ALPR vendors) to obtain all records tied to their license plate and to request deletion where legally permissible.
  • Core value proposition: Empowers citizens to exercise privacy rights and reduce the surveillance footprint of private ALPR companies.

Details

Key Value
Target Audience General public concerned about license‑plate tracking, privacy‑law practitioners
Core Feature Automated request letter generation, status tracking, template responses, secure storage of received data, deletion‑request workflow
Tech Stack Node.js/Express, TypeScript, MongoDB, Auth0 for user auth, AWS SES for email, GDPR‑compliant hosting
Difficulty Low
Monetization Hobby

Notes

  • Users expressed frustration that “Flock is intended to be searchable by law enforcement, not Joe Average” and wished for reciprocal access – rootusrootus, caconym_
  • A tool like this directly addresses the call for “actual legislation that tightens considerably how available the data is to be searched” – rootusrootus
  • Practical utility: enables individuals to know what data is held on them and to act on it, fostering informed debate about data retention policies.

CrowdMap Flock: Community Surveillance Camera Locator

Summary

  • A crowdsourced map and mobile app where users can report locations of Flock (or similar) ALPR cameras, verify via photos, and receive alerts when new cameras appear in their area.
  • Core value proposition: Gives communities visibility into where surveillance is deployed, facilitating informed protest, removal campaigns, or situational awareness.

Details

Key Value
Target Audience Neighborhood associations, civil‑liberties groups, tech‑savvy residents
Core Feature Map‑based reporting, photo verification, trust scoring, push notifications for new camera sightings, exportable data for advocacy
Tech Stack React Native (mobile), Mapbox GL, Firebase/Firestore, Cloud Functions for moderation, optional AR overlay
Difficulty Medium
Monetization Hobby

Notes

  • Commenters highlighted the desire to “track locations of flock cameras” and “destroying/removing them” – infinite_spin
  • The idea reflects the sentiment that “people should be allowed to run a surveillance system” and know where it exists – vamos_davai, shortstuffsushi
  • Potential for discussion: raises awareness of surveillance density, provides concrete data for policy change, and can be used to coordinate physical removal efforts where lawful.

PoliceFlock Transparency Toolkit

Summary

  • An automated FOIA/request generator that helps citizens and journalists request police department Flock ALPR logs, aggregates the responses, and publishes anonymized usage statistics (e.g., frequency of queries, targeted plates).
  • Core value proposition: Shines light on potential misuse of ALPR data by law enforcement, supporting oversight, accountability, and informed policy reform.

Details

Key Value
Target Audject Journalists, oversight bodies, civil‑rights NGOs, data‑driven activists
Core Feature Template FOIA letters per jurisdiction, response parser, dashboard of aggregated metrics, public API for researchers, anonymization pipeline
Tech Stack Python (pdfminer, pandas), PostgreSQL, Vue.js frontend, AWS Lambda for scraping, redaction library (e.g., Presidio)
Difficulty High

Notes

  • HN users pointed out abuses: “redwall_hp: There's a list of 81 known instances of police stalking romantic interests…” – shows need for oversight
  • The call for “actual legislation that tightens considerably how available the data is to be searched” – rootusrootus aligns with this tool’s goal of exposing current access patterns
  • Practical utility: provides concrete evidence for advocacy, fuels public debate, and can guide legislative efforts to curb misuse.
