“Get ‘em out of their “jurisdiction” and they’re fair game.”
Not likely, they stick together for the most part, at least here is CA if you flash your badge it’s a free pass. The only exception is the CHP (California Highway Patrol) they ticket everybody (except their own) and are generally despised by the other LOEs for that breach.
Here the Fuzz have little black-blue-black stickers on their cars as a recognition symbol. A little less blatant than the FOP license plates.
