This is a fundamental disagreement I have. Just because a cop says something it doesn't magically become law. Just because he wants something and I don't give it, doesn't make it illegal. His words and will dont make law. That is the opposite of the rule of law.
He can arrest me, but he can't tell me to sit on the curb if I want to leave. Arrest me or fuck off I don't have to take your orders.
I am glad you made his comment, because it is the exact point I am normally trying to make and I can't ever hit it exactly. Suffice it to say i feel the exact opposite of your quoted statement. I would live to hear the law that says you have to do whatever a cop says. (And I don't mean suck his dick if he says, I mean basic shit like stand here, answer this.)
