  That (C) may admit of exceptions does not, of course, show that (C) is not generally sound. I suggested above that, where (C) does apply, it entails (MR). How much mens rea (C) requires is a further question. Take the offence of causing death by dangerous driving. The actus reus of the crime requires two things: \(D\)’s driving must exhibit deficiencies that we reasonably expect a qualified driver to avoid, and those deficiencies must cause the death of another person. Some think that (C) calls for two mens rea requirements: \(D\) must have been aware of the deficiencies that made her driving dangerous, and she must have been aware of a risk that they would cause death. The idea that each actus reus element should have a corresponding mens rea element is known as the correspondence principle (Ashworth 2008). Whether (C) in fact supports that principle is a matter of debate. It is sometimes the case that the risk of causing some harmful outcome (like death) helps make it the case that an act (like dangerous driving) is wrongful. There is an internal connection, in these cases, between our assessment of the act and the risk of the outcome. Some claim that where this internal connection exists, \(D\)’s awareness that she was engaged in the wrongful act establishes that she is culpable for the harmful outcome. If this is right, \(D\) need not have any mens rea as to that outcome in order to be culpable for it when it occurs: the correspondence principle cannot be derived from (C) (Simester 2005, 44–46; Duff 2005, 143–147).
