If as you say your financial security is an acceptable loss for upholding the constitution then try a simple exercise;
For just one month record every minute you're on duty, even if it's only audio.
At the end of the month review the recordings with a liberty minded constitutional lawyer.
At the very least I'd bet your eyes would be opened, at best you'd have compiled more evidence of unconstitutional behavior.
Do ya' have the guts to go against the status-quo?
