One can pretend that the advice from you tube is correct and give the police a lot of cuss words and insults when he pulls you over, the you can pretend that the Bill of Rights give you protection so that he can not pull out a "throw down pistol" - untracable of course - out of his ankle holster and put a bullet in your stupid head with his gun, then he throws the other piston on the ground so he can say that you pulled that gun on him. Perhaps you are a young shit who thinks what I am saying is a lot of shit. About 47 years ago I hung out with a lot of cops: don't ask me why; because, I haven't figured out why I was hanging out with them. They all bragged about having a throw down piece. The had secret call codes, incase someone got into a shooting and needed a gun to say it belonged to the guy they shot.
OK, Now that I have told you the situation that can make you dead sooner than you can fart on a dark road, late at night, with no one around except the two of you.
It never hurts you to be extremely respectful to a cop: someone who is in a job because he is seeing respect, and he wants to be incharge of just about everything. A blustering Idiot that craves respect could be one of the 15 to 20% (10% is widely documented, but I think it is higher so I listed 15% to 20%) of the truly crazy individuals who are members of the police force.
The last time I was stopped I said:
"Good evening Sir: I don't quite understand; I was not speeding, and there hasn't been a stop sign for several blocks. Can you please tell me why I was stopped."
They really like being called Sir, and they like the respect - use it.
He smiled back at me an said that the lower beam on my head light went out when I switched from high beam to low beam as he approached me. The warning ticket was better than a real ticket.
He did ask me where I was going (I know it is silly - just let it go.) I not only told him I the name of the nearby grocery store I was going to, but what I was going to purchase.
(Who cares if it is none of his business. Who cares if he is fishing for other information. He is probing you for information, and to see if you are nervous.)
Be nice and respectful. It doesn' hurt you, and the results for you are much better than being an ass hole.
