First, I'm not a federal police officer, I'm an Inspector. I'm also a reserve deputy locally, so I carry two sets of creds. Second, I have a warped sense of humor. If you haven't figured that out by now, then you haven't been paying attention! But, I didn't make a joke about shooting federal police officers. I simply pointed out a vulnerability in considering the use of armored vehicles. It's nearly impossible to make an arrest from inside one.
FWIW, my "leadership" is fully aware of my "uniqueness". I used to scare the living bejeezus out of them, but over time they've come to understand that I have my own unique code of conduct and an overly developed sense of justice. I'm not the threat, I'm the one that evaluates potential threats and mitigates vulnerabilities to reduce risk. Again, the people I work with both in and out of the .gov know where I stand. If I were the problem, I wouldn't still be where I am, nor would I have their confidence.
That's assuming that an arrest is the primary goal.
