I can only speak to my own situation prior to my retirement.
At the time we completed something that was called the integrated fisheries management plan that included conservation, protection and enforcement as part of the model. It was run primarily by the areas.
Just to give you some of my own experience, I had disagreements in the past from some of my masters at regional headquarters who had a different idea of how enforcement should have been conducted. At one time I said to them, “If you don't agree with what we're doing, please put it in writing. I want your direction in writing. Unless I get it in writing, I'm going to continue to do what I'm doing", but I never received it in writing.
If I had received something that I disagreed with or thought was illegal or immoral, I would have resigned, and I would have made it widely known why I was resigning.
