I know they had to get a judge to rule that they are public records before they got all of them. I don't know what the public records law are in Washington.
At least in Utah [63G-2-305 section 63](
https://le.utah.gov/xcode/Title63G/Chapter2/63G-2-S305.html?v=C63G-2-S305_2025110620251206) states captured plate data that is obtained through an automatic license plate reader system used by a governmental entity as authorized in Section 41-6a-2003. And in [41-64-2002](
https://le.utah.gov/xcode/Title41/Chapter6A/41-6a-S2002.html?v=C41-6a-S2002_2025010120240501) the definitions portion of 41-6a-2003 "Captured plate data" means the global positioning system coordinates, date and time, photograph, license plate number, and any other data captured by or derived from an automatic license plate reader system.
Also, in [63G-2-305 section 10 basically gives enforcement agencies a lot of discretion to invalidate requests for internal audits, even if such audits don't contain protected information, the audit itself is protected particulary under (e) the audit it protected if it "reasonably could be expected to disclose investigative or audit techniques, procedures, policies, or orders not generally known outside of government if disclosure would interfere with enforcement or audit efforts" like what audit isn't going to have audit techniques included in it....
I may have tried a GRAMA request or too regarding flock :)...
