License Plate Reader: 5 Billion Scans in 2024 (No Warrant)
The short version: Signal Decay's breakdown of the warrant-free ALPR pipeline is a solid primer on how routine drives become permanent, searchable records.
Our Take
Signal Decay's rundown lands on a truth we hammer on constantly: the scale of license plate reader surveillance in this country isn't hypothetical, it's industrial. Billions of scans a year, run largely by private vendors like Vigilant Solutions and its competitors, feeding databases that sit outside the warrant requirement most Americans assume protects them. The video does a good job walking through why that gap exists — ALPR data is treated as a business record, not a search, so the Fourth Amendment barely applies.
What matters for our readers is what happens after the scan. Once your plate, timestamp, and location hit a vendor's server, it doesn't just serve one police department — it can be sold, shared, or queried by agencies you've never heard of, with retention policies that vary wildly and oversight that's often nonexistent. That's the data broker angle Signal Decay digs into, and it's the part most local news coverage skips.
If this is news to you, it shouldn't be — there's likely a camera doing this exact thing near your house or your commute right now.
