More legal causation: accessories

In ‘Legal Causation’, I proposed a new account of legal causation. Here, I extend and supplement that account to cover the actus reus of both principal- and accessory liability. The upshot is a new account of criminal liability for result crimes. It holds that the defendant is liable for, e.g., the victim’s death if and only if the defendant culpably either killed the victim or increased the risk that the victim would die. My pitch is that the account well-captures the central, settled tenets of criminal liability and that it does so in a metaphysically simple and principled way.
