Okay. That's fair enough.
Mr. Fryer, thank you for your testimony here today. You gave us a number of statistics about the number of people who get tested. Give us your view of how effective this is. Is this something that has worked in your state in Australia to stop people from taking drugs, or is it just a better recognition that there are people out there taking drugs?
Does it have a preventative effect? That's one of the things we're looking at in terms of mandatory testing. It's not just a question of finding the people who have alcohol or drugs in their systems, but it also hopefully discourages people from taking a chance. What are your views on that?
