"Police have both extra constraints and extra permissions - on the one hand, they can't dodge involvement in social disorder as the rest of us can and they may be required to conduct themselves privately in a way that does not undermine their public authority; on the other hand, they have permission to engage in deceptions, invasions of privacy and uses of force that are forbidden to the rest of us. But this does not put them beyond common morality."
