Former Director of National Intelligence, Tulsi Gabbard, gives a speech outlining the mechanics of the Deep State and how the people within it operate.
At around 3:30 of the presentation, Gabbard gives a specific example of the attitude of the employees on assignment to the ODNI.

The poster story… if I were her Chief and was told a presentation fro the President was locked in a desk, guess how long it would take me to procure a hammer or crowbar and extricate the item. I would first have him escorted from the room… to prevent me from doing time in Leavenworth.
My exact first thought upon hearing her tell the anecdote.
Gag him, handcuff him, place a black cloth bag over his head, and perp march him out of the facility into a vehicle to take him to a holding cell to begin immediate termination with prejudice for antagonistic and unjustified insubordination against legitimate orders from his chain of command superiors.
