Why you are a FBI agent.

Yes you are indeed a FBI agent, a Federal Body Inspector agent. Why you even have a badge and everything. That is more than enough to convince people that you have every right to inspect their body as you please, because surely no one would lie about that. So go off and inspect bodies however you see fit. You command a position of authority or so you say, and if you know how to use it right you can do all sorts of things.
