You do have to take direction from an officer of the law, that is certainly true, no arguments there.
However how far does that extend? That is what is in question here.
It would be good to see the actual law referenced that states this. And also the punishment/fine associated. I mean if it's only a $100 fine. Fk that, I'd simply pull the keys outta the ingition and walk off. They aren't allowed to tow it if it's legally parked.
Without it, it's speculation. I've proven Smokey to be incorrect a few yeras back in that thread on NS (dont go there these days), so he is definately not always right.
