The role of criminal law is to identify, discourage, and, when necessary, punish behavior that harms other people or otherwise threatens the very fabric of civil society. In order to be legitimate, a criminal justice system must accomplish those tasks in a way that is substantively and procedurally fair while ensuring accountability from government officials who abuse their authority.
