Goodness knows, but what sort of person would do that for a living?
Actually, it's probably the sort of thing that steals up on employees, so you might start as a basic 'general' civil servant or health admin worker, who gradually moves into a role in the department of WhateverItIs, and the Accuse forms are just some of the ones you process, until there is a chance of promotion to supervisor at an extra dollar an hour, so you take it, and the next thing you know it's been re-organised so that Accusations and Prosecutions have become a department of its own. Five years later you are leading that, and there's a certain satisfaction in being able to make decisions about other people's lives - I mean you're a reasonable person after all, and some people would be much more draconian.
It's important that you keep your stats up, as some of those younger people are ambitious and snapping at your heels. You really have to come up with new initiatives to impress your boss at the monthly meeting of departments heads, so you wrack your brains and come up with ideas to turn neighbours against one another and let them settle feuds at a stroke. . . .
