The X-Files, Season 1

Section Chief McGrath:
Why did you countermand my decision? Mulder's conduct was in clear violation not only of bureau procedures but of federal law.

Deep Throat:
Yes.

Section Chief McGrath:
I don't understand. The committee's case was air tight. You've ruined the last best chance we had to get rid of him.

Deep Throat:
I appreciate your frustration, but you and I both know Mulder's work is a singular passion-- poses a most unique dilemma. But his occasional insubordination is in the end, far less dangerous.

Section Chief McGrath:
With respect sir, less dangerous than what?

Deep Throat:
Than having him exposed to the wrong people. What he knows... what he thinks he knows... Always keep your friends close, Mr. McGrath... but keep your enemies closer.
