Outdated Flock alert leads to police stop of people not connected to homicide investigation
A stale Flock alert tied an already-cleared vehicle to a homicide investigation, leading Brookfield officers to conduct a guns-drawn traffic stop.
Flock Safety operates the largest automated license plate reader (ALPR) network in the United States — and it's watching you right now.
Every time you drive past a Flock camera, it captures a high-resolution photo of your vehicle, reads your license plate, and logs the exact time, date, and GPS location. But it doesn't stop there — according to Flock's own FAQ, their cameras use machine learning to extract far more than a traditional license plate reader.
This isn't speculation — this is what Flock advertises. The data is stored for 30 days or more, shared across thousands of agencies nationwide, and can be searched by any officer with access — often without a warrant.
What a Flock camera captures every time you drive past.
Over 80,000 Flock cameras are deployed across 5,000+ cities. Your movements are tracked whether you're a suspect or not. You were never asked. You were never told.
ALPR misreads have led to families being pulled over at gunpoint, handcuffed, and detained — because the system confused their plate with someone else's. It has happened dozens of documented times.
Police officers have used Flock cameras to stalk ex-partners, track personal enemies, and monitor people with no law enforcement justification. Audit logs are rarely reviewed.
Flock data has been accessed by Immigration and Customs Enforcement and other federal agencies, raising serious concerns for immigrant communities and sanctuary cities.
Most cities adopt Flock cameras with little to no public debate, no privacy impact assessment, and no policy governing how the data is used, shared, or retained.
Flock's newest product, NOVA, goes beyond plates — it creates a "vehicle fingerprint" that can identify your car even without reading your plate. This is where it's headed.
