It's more common than you might think, even in the US. A common example I see is major cities where the freeway speed limit is 45 or 55, but everyone is doing 70 or 80mph, even the police officers. Most of the time that cop will drive right past you even if you're doing 20mph or 30mph over the speed limit, but if they want to pull you over, now they have a free reason to arrest you and impound your car. But if you're driving the speed limit while everyone else flies by you, you could be pulled over because driving too slow is suspicious.
It seems that, given enough time, governments will find ways to implement enough contradictory laws that everyone is a criminal.
