This hardly seems like a deontology vs utilitarianism thing. You can justify both those positions and their opposites under both systems.
E.g. i'm pretty sure every traditional rule system recognizes "inter arma enim silent leges" to some extent or another. I suspect those who claim they don't at all aren't really following a rule system so much as making things up as they go and doing whatever is convinent.
