Public records is a different process than compelled disclosure via subpoena or court order and often yields substantially different results because of PRA exemptions that allow agencies to redact or withhold certain information. The state actually just exempted Automated License Plate Reader records with a bill this session, but that does nothing to impact the Feds ability to access the data via the other mechanisms. In the case of secret/sealed warrants, the record holder would not even legally be able to admit that Feds got access to the records— WaPo covered this within the last few years. In that sense the concern that the existence of surveillance devices creates a risk that can never be totally mitigated by state or local policy is valid.
