The residents of Eugene may be regarded as left leaning (as in peaceful, go along get along) but that appears to also mean naive and easily manipulated.
Lazzar for mayor!
The only alternative would be a whisper campaign to suss out the trustworthy pockets within the existing police apparatus, but that is probably even more dangerous. Imagine the police chief in your city going public with information that there is a left wing plot to overthrow order from within the police department!
UK and EU politicians are also liars, but some are only so out of necessity. I see corruption here too, but I also see people trying to go the middle road and do what they believe is right. I do not see that in the USA.
You only have visibility through a lens that is intentionally showing you only the most click-worthy perspective. In real life there are plenty of people trying to do what they believe is right. But it's hard, thankless work, because even when they succeed someone or another will claim they are biased, etc.
If you identify as being on the left, you should identify with wanting the police to answer FOIA requests, and you should be happy to be associated with this.
