Tens of officers have been fired, and some even arrested, for abuse of the Flock AI-powered license plate reader (ALPR) camera systems used by police departments throughout the U.S. 404 Media reports on this purported surveillance abuse, and reckons that the tens of Flock-assisted stalking cases tallied by investigators are just the tip of the iceberg. It also shares details of several cases where police officers go Flock crazy, repeatedly using the system hundreds of times to check on the activity of (ex)romantic partners.

The source report starts with the example case of Jarmarus Brown, an Orange City, Florida, police officer. Investigations reveal that Brown looked up his ex-girlfriend’s (and her close family members’) license plates over 100 times while on patrol. The police officer’s colleagues commented on the activity to Brown, hoping he would stop, and he indicated that he would. However, Brown couldn’t resist stalking using the easy-to-access Flock.

When he was eventually found out by authorities, Brown admitted he’d been "dumb" and blamed his emotional state for his Flock abuse. Research into this case revealed Brown was a very controlling person. For example, the source report says he would insist his girlfriend stay on FaceTime, even during work hours. He also put an AirTag in her wallet.

This wasn’t a one-off. 404 Media outlines several examples of police Flock abuse in Wisconsin, Missouri, Georgia, and Kansas. Most cases are pretty similar to that of Officer Brown. Obsessed romantically shunned police officers stalk (ex) partners using Flock for months or years before being found out. Mostly, their indiscretions come to light as a result of action from the person being stalked – a complaint, private investigation of some kind.

What we see on the surface is “almost certainly a vast underreporting of the overall abuse,” says 404 Media. This is because only the most egregious cases leading to police being fired or arrested would result in proper investigations and the documenting of the underlying issue.

Flock Security says that with 140,000 monthly active users, abuse is “rare.” It fights lawsuits and potential regulations, which would mean police need a warrant to use Flock. However, police departments allegedly rarely call out Flock abuse. Most complaints come from “victims who have found patterns of abuse in public records files they have obtained from their local police departments,” notes the source.

If you suspect you are being stalked, HaveIBeenFlocked.com is a good place to start by inputting your license plate number. The site has a searchable database of Flock ALPR inquiries released via public records requests. The site’s future could be uncertain, though, as 404 Media says that Flock Security “has repeatedly tried to get that website taken down.”
