This is going in a similar direction to the one I had on another forum. An officer makes a statement about what he'll do if everyone doesn't meet his expectations of total submission.
It's reasonable for an officer to take steps to enforce laws when they are violated, and farmerboy's comments would have been fully accurate as recently as 30 August 2009. Failing to inform would have warranted a citation and possible CHL suspension at that time.
There are a lot of laws on the books and they change from time to time. It's not surprising that a person, even an LEO might not be 100% up to date on every single law for his state, especially ones that have changed recently.
That's one of the useful aspects of these discussions. They can either provide information or prompt a person to investigate/research a topic and thus become better informed.
