I'm in CA and have friends that are firemen and cops. Generally they respect each other and think of each other as being a brotherhood, and usually guys like this particular CHP officer are hated by even their fellow cops. There is a cop here that is notorious for giving DUI's to fellow cops and to firefighters.... I'm surprised he hasn't died in an 'accident' of some kind.
I've heard there are fire/police rivalries in some towns, but from the people I know, it does not seem common here. I think this particular asshole cop is an exception. Guys like that make cops look bad. There are a lot of good police officers out there, but it's so easy to focus on these guys (and guys like that dickhead who shot the dog that was on a leash down in LA).
