Flock<br>Cops Keep Getting Arrested for Using Flock to Stalk People

There have been more than a dozen cases around the country where police use Flock to obsessively and illegally stalk people.

For months during the summer of 2024, Jarmarus Brown, an Orange City, Florida police officer, ran his ex-girlfriend's license plate through the Flock automated license plate reader (ALPR) system lookup database at least 69 times. He searched for the license plate belonging to her mom at least 24 times, and searched for the license plate belonging to her dad at least 15 times. Brown’s searches were happening so often, and were so commonplace, that even one of his colleagues noticed Brown researching his ex-girlfriend's whereabouts while the law enforcement officers sat in their police cruisers, according to court records obtained by 404 Media.<br>“While they were sitting there, Officer [Shadrich] King noticed Jarmarus was on the Flock system and a license plate reader image of [Brown’s ex-girlfriend] was on the screen,” a police affidavit about Brown’s behavior obtained by 404 Media reads. “Officer King said he mentioned to Jarmarus that he needed to stop running her vehicle in that system because he could get in trouble. Jarmarus responded saying that he knew that, and he was going to stop.” Flock’s automated license plate readers document every car that drives past them, creating a broad network of people’s movements around the country. Police can then look up license plates to learn where a specific car and, by extension, person, has traveled over time.<br>On another occasion, Brown told King that he believed his ex was lying about her whereabouts. She “told Jarmarus she was at her house with her mother, but Jarmarus knew for a fact she was not. When questioned by Officer King as to how he knew for a fact she was lying, Jarmarus said he used the Flock system and saw that her vehicle was elsewhere,” the affidavit reads. “Jarmarus then asked Officer King if he wanted to join him on a ‘stakeout’ to try to see where her vehicle was located.”<br>According to Brown’s ex-girlfriend, while they were dating he would “constantly require [her] to either be on FaceTime with him or be on the phone with him, even while she was working […] Jarmarus would try to control aspects of [her] life, such as the amount of makeup she would wear and the length of her fingernails.” According to the affidavit, Brown’s stalking extended beyond license place lookups; at one point while they were dating, he put an Apple AirTag in her wallet. But the bulk of his surveillance came through Flock, the affidavit says, noting that he kept “randomly showing up at the places she was at.”<br>The affidavit states Brown told investigators that “he would occasionally run her tag through Flock to track her whereabouts” because he believed she was lying to him. “It was dumb as hell on my end, emotions flowing, mind going,” he told investigators. The investigators ultimately determined Brown “knowingly and intentionally accessed the password protected computer systems, Flock and DAVID [a Florida DMV vehicle information database], to run the license plates of vehicles [she] frequently drove, for his own personal reasons. There was no work related, justifiable, reasons to do so, other than to track [her] whereabouts.” Brown was ultimately charged with stalking and hacking-related charges; he served one day in prison and was sentenced to five years of probation.<br>Brown’s case was not a one-off. Local news reports from around the country repeatedly detail police abusing the Flock surveillance systemic order to stalk their partners or ex-partners. The contours of each story are much the same, with the police officer in question using their access to the system to repeatedly track a specific person over the course of weeks or months. The cases highlight the fact that Flock can be used to track the whereabouts of individual people, that police do not get a warrant in order to use the system, and that, if they have access to the system, they have the technical ability to look up any license plate they want for any reason they want. An April study by the civil rights group Institute for Justice found that at least 18 police officers have been caught around the country using Flock to stalk a romantic interest in the last few years; another database, called the ALPR Abuse Library, has documented 20 specific cases of “stalking/targeting” around the country.<br>The known cases of police stalking are almost certainly a vast underreporting of the overall abuse, because they largely include only cases in which the behavior was so egregious that it...
