(TEXAS TRIBUNE) - Amid growing privacy concerns over Flock cameras, a Texas man has asked a federal appeals court to toss out his armed robbery conviction and 60-year prison sentence, arguing that the AI-powered camera system gives law enforcement more surveillance power than the Constitution allows.

Police used Flock cameras to link Charles Brownlee to five armed robberies across several Dallas-Fort Worth suburbs in 2024 by compiling a "pattern of life" that traced his travels along North Texas roads monitored by Flock's vehicle-scanning devices.

The data gathered is so extensive and invasive that police should be required to obtain a search warrant, approved by a judge, before rifling through Flock data, Brownlee's lawyers argue."No mortal human has ever possessed" such an ability to effortlessly and immediately reconstruct any person's movements, Brownlee lawyer Matthew Wright told the 5th U.S. Circuit Court of Appeals during oral arguments on Oct. 5."I'm not sure that the full capabilities of these systems have been either revealed or litigated," Wright told the three-judge panel in New Orleans.
