Flock says its new tool will help identify police abuse, but hasn’t explained how it works

Surveillance technology startup Flock announced a series of new policies and tools on Thursday, claiming they will help curb abuse of its automated license plate camera reader systems and help keep its law enforcement customers accountable.

Flock is now recommending police departments retain data for seven days rather than the previous 30 days. Along with this change, the company introduced what it calls “Evidence Mode,” which can be turned on when customers need to retain data for longer periods in “exceptional cases” and requires a specific case number. Customers will also now be able to set limits on the data they share with other customers based on the type of offense that’s under investigated.

The company also highlighted a tool called “Audit Assistance” as one of the key changes. Flock launched the tool in April. Since then, Flock said “more than one-third” of its customers have turned it on, and the startup is now requiring all customers to enable it by the end of the year.

Flock said Audit Assistance “detects abnormal activity and flags it for Administrator review,” according to a blog posted released Thursday. If that happens, the tool can automatically lock out users who have been flagged until an administrator intervenes. According to Flock, the tool has already helped customers spot and stop abuse.

Several executives have touted the capabilities of Audit Assistance. But despite its stated importance, Flock has not explained in detail how Audit Assistance actually works.

Some official comments provide some understanding of what Audit Assistance can do; it gets vague when trying to determine how it does it.

For instance, Flock’s head of trust and compliance Ashley Haber said in a video that the Audit Assistance can flag “what may look like an odd search history from a specific user,” helping customers understand how their users are operating the system. In another video , Flock co-founder Paige Todd said “Audit Assistance actually flags unusual patterns early. Think a user searching the same plate repetitively for more than 30 days.”

And Major Patrick Krieg of the Dunwoody, Georgia Police Department, a Flock customer, described the feature in a press release as “an algorithm that has notified us of any type of bias.”

Flock describes Audit Assistance as a feature that can “surface atypical activity early and review it quickly with a clear, documented workflow.”

What’s unclear — and TechCrunch has asked for answers about — is how this “algorithm” actually works, what data is it trained on, and if it was developed using an large language model. TechCrunch also asked what kind of patterns is it designed to surface and what exactly gets flagged as “abnormal activity”?

According to Flock, Audit Assistance is not based on [Machine Learning] or AI. The company told TechCrunch that “It is a data tool that flags atypical search patterns for further review. One example that would trigger a flag is if a user searches for the same plate using multiple different case codes, as this could potentially indicate abuse.
