I echo what Tom said. Obviously most jurisdictions in the country have looked at all three of those, including criminal record checks. Obviously some work has to go into that.
An interesting one if you really want to look at revenue, if the issue is revenue.... I think you've heard all three of us say that maybe we need to focus within and see how we redirect resources first. I've been a big believer that if we're going to get into evidence and outcomes and we're going to pay for those things that have been evaluated and so on, then if you want to take the driver of our business, put a 1% tax on alcohol at $200 billion a year. That would be $200 million, and you would pay for everything and then some. The problem is you would have to make sure it was focused on the things that matter.
