In this episode, we follow our wayward enforcement agency as it tries to make up for its misdeeds by issuing subpoenas after the fact. Maybe next episode they'll shoot somebody, and afterwards begin an investigation on whether they were a criminal or not. We're cool as long as we can fudge the paperwork, right?
At least the FBI has rules against this sort of thing. They at least try to be good, even when they fail. Not so much with some of the other gubmint agencies.
