The ACLU continues to urge that default retention periods be shortened to 48 hours — not one week. And they warn Flock allows longer retention to any police department that asks for it, or when police officers activate "Evidence Mode" (the scope of which is not yet clear):
Even if "Evidence Mode's" data retention hold only applies to hits returned on a given search, it would still retain significant amounts of location data on persons and vehicles who law enforcement do not suspect have engaged in any wrongdoing...
Flock claims that its changes will provide "more local control," meaning local police can decide what types of offenses other Flock customers can search their data for... This is not new. Flock has attempted this before, and the security measure failed because users were easily able to circumvent the system's requirement that police input the purpose of their search. For example, on June 12, 2025 Flock started claiming its new "Proactive Search Term Tool" would block any "impermissible" searches, such as abortion-related searches in states like Illinois that prohibit sharing reproductive healthcare data. But police officers quickly realized they could just input "investigation" or even "hehehe" as a search reason and it would be approved. Flock later switched from an open text box to a drop-down menu of reasons, but that just offered police a list of acceptable purposes they could choose from, whether it was accurate or not. Until Flock demonstrates they can develop a reliable, workable system to prevent improper searches, this promise of local control provides nothing more than a false sense of security...
While providing "Audit Assistance" to all departments makes sense, there is no evidence that the tool works consistently to address what the Washington Post observed is a growing pattern of police officers turning Flock into a personal stalking tool. While dozens of officers have recently been arrested, fired, or otherwise disciplined for misusing Flock for personal reasons, Flock claims these arrests are proof its auditing tool works. However, unless we know the number of officers misusing the system, we cannot conclude if Flock and its auditing tools are catching 95 percent of violators or 5 percent. Flock needs to have its auditing tool analyzed by an independent evaluator to determine its actual effectiveness. Until then, we don't know if the tool is a real security measure or just window dressing.
Perhaps the oddest part of Flock's announcement is its claims that "now every search will require" police to input a case code... While claiming that a "search without a reason is a search that shouldn't happen in the first place," Flock's announcement fails to note how easily users have circumvented "search reason" security measures in the past... This leaves the public wondering how making an ineffective voluntary security measure mandatory will improve its functionality.
Flock's "nearly $1 billion in venture capitalist funding has locked it into an operational model that seeks to trade our privacy for massive profits," concludes the ACLU's statement, as they promise to continue "The ACLU is fighting alongside communities to cancel local ALPR contracts and push lawmakers to protect our rights from this surveillance nightmare..."
