I'm a nobody, but I imagine the feds or spooks would never use anything like that on someone they have physical access on. If the target is in their jurisdiction or a blacksite and it's that important, a lead pipe is easier.

IF they can decrypt stuff, they'll only use it when it's has an actual benefit beyond a conviction and the keys are truly inaccessible. (e.g., person is dead, the keys are in an enemy state HSM, etc.)
