I detect from your sarcasm that you believe they are. Its not about being above the law or not. Its the professional courtesy that is extended. Beware that parole officers and firefighters will get less courtesy than a fellow brother in blue (police officer or sheriff). With that said theres still no guarantee that you won't get a senior officer that will pull you over, won't write you a ticket but will get in touch with your commanding officer and he will ream you out.
Whatever the case having a badge is not a hall pass to do whatever you want without repercussions. Police officers are usually (or should be) held to a higher regard.
what if i was the commanding officer? haha
