And if you can’t because they’ve been moved or “mysteriously misplaced,” charge him for grand larceny and arrest him (IANAL so there is probably a better legal term for this).
I don’t think that “sure, I stole from them, but I “lost” what I stole so we cool now,” is a valid legal defense. But I’m not a disbarred lawyer, so I could be wrong.
Because if they start holding others in similar offices to account, they might have to hold themselves as well, and that ain’t happening.
