Apologies if there is already a thread addressing this question -- please feel free to link it if it exists. Also, should this be in Setting Development? Mods? Google is not being very helpful with this one. Let's pretend an undercover FBI agent gets arrested by regular cops for Really Bad Stuff (TM), like the kind of Stuff that would certainly get you life in prison. Since Really Bad Stuff (TM) would have been approved and facilitated by the FBI beforehand, would they have the realistic authority to set that person free again? Is there an appeal process of some kind? Can the FBI people just call the police/jail and be like "Hey we knew about this and we're fine with it, we need them to be undercover-ing, okay?" I have no idea how the legal system in my own country works. Hooray for public education!
