Dr EMILY HENDERSON: Don't do that—was saying, it goes to that mens rea / actus reus aspect. I really would like you to spend some time talking to us about your thoughts about how we got to that definition because, as my colleague Vanushi Walters said, it's actually very close to your original. In the end, after all that, we circled back after all that discussion. But for me, "act proven"—and "proven" was the word that became a real hiccup because proven suggests that the crime was committed, and for a crime to be committed, of course, you've got to have both those things: the actus reus, the act, and you've got to have the mental intention. A person who is insane cannot form that mental intention and traditionally, by that very nature, that is it, they are not an offender. They can be accused, but they cannot be convicted of the offence in the traditional way.
