regardless if they agree or not they will following orders. I really doubt that any of the sheriffs speaking would leave it up to the officers discretion to arrest or not arrest someone for CC. You are also as a cop a direct reflection of your department and superiors.
I'm not sure if you've ever worked in law enforcement but I would bet you haven't. The chief/sheriff is generally not on the scene when the cop on patrol is doing his thing. But it really doesn't matter what I say. People who are anti-cop will always find a way for their position to be right, even when it isn't.
