You could file a civil action for violation of constitutional rights, but under Roberts, SCOTUS has basically been ripping out all of the mechanisms that would let you file such suits.
You can file with the police, if they take it. You can also file as a private criminal complaint in many jurisdictions. However, it's up to the DA to approve it most of the time. There can be an appeal process where a judge would make a determination.
But yes, if the whole system is corrupt, then there's not much to do.
IIRC there was a point in time roughly around ~2017 when it happened in Redmond WA (i.e., in the town that the Microsoft HQ is in). I might be off by a year or two, but it doesn't really change the overall point.
TLDR: in under 2 years, that whole red light cam initiative got canceled and reverted, because the local stats showed that it just made things more dangerous on the roads (by significantly increasing the rate of rear-ending accidents at traffic lights).
