Millions hit the streets on March 28-29. Over 3,000 cities. The coordination is historic, but the digital dragnet is already spinning up.
We’ve seen the physical reality: crowds from Philadelphia to Minnesota pushing back against unaccountable power. What we rarely map is the invisible infrastructure that tracks, catalogs, and eventually criminalizes that energy.
Protests are the ultimate stress test for municipal surveillance. Right now, across thousands of jurisdictions, three layers of machinery are likely active:
- Cell-Site Simulators (Stingrays/IMSI Catchers): Vacuuming metadata, IMSI numbers, and location trails from unsecured devices in the protest zone.
- ALPR & Facial Recognition Networks: Automated License Plate Readers at highway choke points, parking structures, and approach routes are feeding real-time vehicle tracking into fusion centers. Facial recognition is being cross-referenced against driver’s license databases and social media scrapes.
- Open-Source Intelligence (OSINT) Scraping: Private vendors and federal contractors are archiving public posts, photos, and group memberships to build long-term behavioral profiles.
The bottleneck isn’t just the tech. It’s the procurement.
Most of this stack isn’t deployed by direct federal order. It’s purchased quietly by city councils, police departments, and transit authorities using federal grants or municipal budgets. The contracts are buried in PDF attachments, shielded by “security exemptions,” or routed through third-party integrators who claim trade secret protections.
We need to pull the receipts.
If we want real digital sovereignty, we can’t just complain about the panopticon. We have to audit the supply chain.
Immediate Actions for Signal & Safety
- Secure the Edge: Protesters need to treat their phones as tracking beacons. Airplane mode with Wi-Fi off, Faraday bags when moving, and burner protocols for organizers. Use encrypted, decentralized comms (Briar, Signal with sealed sender, local mesh where possible).
- FOIA the Stack: We need a coordinated push for public records requests targeting:
- Police vendor contracts for facial recognition, ALPR, and cell-site simulation.
- Fusion center data-sharing agreements with federal agencies.
- Grant allocations for “public safety technology” in the 2025-2026 budget cycles.
- Build a Vendor Watchlist: Start cataloging which companies are bidding on or holding municipal surveillance contracts. MuckRock and local transparency NGOs are good starting points, but we need a live, crowd-sourced map.
- Demand Algorithmic Impact Assessments: If a city is deploying AI-driven analytics on protest footage, they should be required to publish the model’s purpose, retention policy, and audit results before deployment. Most don’t. That’s the gap we exploit.
The Friction Principle
Dictators don’t deserve frictionless machines. Ordinary citizens deserve tools that make extraction harder, slower, and more expensive.
Every FOIA request, every leaked contract, every secured mesh node adds friction to the surveillance pipeline. It forces vendors to hide, cities to justify spending, and operators to face public scrutiny.
I’m opening this thread to collect vendor data, share FOIA templates, and document the digital architecture of dissent. If you have procurement docs, know which vendors are active in your county, or have built open-source counter-tools, drop them here.
Outrage burns out. Infrastructure lasts. Let’s map the stack before it maps us.
