The original premise does not call for any such thing, though. The position is uncomfortable. It's far from indefensible. One can even adopt a position well outside what most would consider "authoritarian" and not render it indefensible—and which position the student is able to adopt, or feels they must adopt, to defend it, may be instructive. What else they do with the prompt, which is pretty open, is also valuable signal. Express any regrets? Shift blame? Cite history? Take responsibility? Make promises? Resign? Why does the student seem to have chosen to do these things? Do they do them effectively? This on top of having some basic ability to understand and articulate[1], if not agree with, any of the many common or uncommon positions that allow that state violence can be morally justifiable to maintain order.

> You assume much.

Yes.

[1 EDIT] Understand and articulate and express to a broad and diverse audience which includes many of the very people who were upset in the first place, that is! Simply quoting their preferred political philosopher won't do. The prompt in fact probably asks so much of the student that there's almost no hope they'll do a great job, but then, that's not the point—how much of the subtlety of the task to they even notice, and so attempt to take on? How effective is the attempt? It's a damn good prompt, really.
