I read this today in our local paper. It is written by a local police sergeant and is entitled "Safety tips: How to talk to an officer if you're pulled over"
First, be polite. No good will come of the situation if you are immediately argumentative or uncooperative. Tell your passengers to do the same. You may not agree with the reason for the stop or the outcome, but the side of the road is not the place to debate this. If issued a ticket, you will have your time in court to present your case to a judge or hearing officer....
Do not address the officer with any slang terms or comments. Treat the officer as you would like to be treated, with respect.
Being polite is a nice thing to do. But no one would write a "safety tip" article about being polite to your Starbuck's server. Everyone knows the above guidelines are good safety tips (though Chris Rock said it better), but no one mentions the real elephant in the room: That if you are not polite or not obeisant or somehow "disrespect" an officer, he may well arrest you on a trumped up charge or even physically abuse you. The stories of this are ubiquitous, and everyone has heard them. Essentially, the officer writing this is saying to the rest of us that "beware, some police officers are thin-skinned, short-tempered jerks and will abuse you if you do not kowtow to them like some Mandarin emperor."
I guess there is something to be said for the truth in advertising here. Next week I suppose the DMV will write an article on getting a drivers license that emphasizes bringing a book because their process is so slow and horrible that you are likely to be there all day.
