I'd like to make just one point now, because it's also in answer to the million-dollar question that was posed from across the table. The issue is that a person, like the perpetrator, should have known, and it's about trying to get inside their head. When it's dealt with as a health and safety issue, that problem, like many of the other problems, disappears. The health and safety legislation doesn't talk about how the perpetrator should have reasonably known; it just says that it can reasonably be expected to cause harm. It doesn't say that's assigned to any individual.
