I agree that it's not clear that this breaks federal law. But I do think it's clear that this should break federal law.

There's an interesting analogy with copyright issues surrounding AI use. Both copyright laws and surveillance were created to (respectively) creative incentives for authors to create novel works; and to protect citizens for indiscriminate surveillance. The laws made sense given the technology available at the time: it simply wasn't feasible to put a cop on every street corner, or to ingest the ideas of every work ever written.

But the laws have been eclipsed by technology. Technology makes a mockery of existing laws, by clearly violating their intent. Much has been written to the effect of "why bother to create new, free materials on the internet when it will just get scooped up by an LLM with no attribution to me." Similarly, Flock cameras have the effect or violating privacy in the exact same way the original laws sought to prevent.

Unfortunately, laws are slow to change, and monied interests will fight tooth-and-nail to put their profits above the rights of ordinary people. It's going to be a difficult decade or so coming up.
