I don't think it's possible to do that. We have to measure it as we go along. We've got to get the data. The data will show—. We've got to have baseline data to begin with, and that's what's so difficult to get, because we can't get that from other countries. Only New Zealand recorded any incidents before they actually brought in the legislation, and they did that for three months beforehand. That's why we've been looking at New Zealand a lot of the time, just to make predictions. But we've got to rely on the data. One of these sub-groups is looking at data, so that sub-group should be very productive, I think. And then we will be actually able to see what happens. But I don't think we can respond to that.
Okay, that's fine. And the last question, with regard to resourcing, just to understand the process of how this ties into the wider budgeting—did you and your officials sit down with the Finance Minister and the First Minister's officials to discuss the costing of this? I imagine so. What was the nature of that kind of discussion?
Some of the costings are decided. For example, the advertising, the awareness-raising campaign—that's £2.2 million over six years. So the decision has been made about that. I don't know if there were further discussions right at the beginning of this process.
There have been discussions. The discussions tend to be positive. We can't really say any more beyond that at this moment in time.
