Seeing as I'm one of the few people in here who's actually spent time in Cotati (TheLorax might be another one, seeing as he's from about 10 minutes down the road) and It's no real different than any other small township near a large city. I for one have never had to deal with the cops there, but everywhere has it's bad eggs.
...on that note, I live in a town that's cotati-ish here in Oregon, and last night I saw a guy get hauled out of the library by 5 cops. They threw him to the ground so hard that his sandal flew at least 10 feet away. It was GNARLY. They then dragged him off.
Granted, he was probably homeless, and probably wacking it or something, but it was a pretty unnecessary show of force. They didn't need 5 guys, and they sure didn't need to throw him to the ground like he was a fugitive. They just have nothing better to do, so they want to be forceful when they can, I suppose..
