Absolutely.
By the way, I didn't just cook this up myself; I've had a lot of consultation with colleagues.
I think the important thing is to get a variety of perspectives, mostly from outside of the people who are running the system. There are four categories. I suggest you call at least one witness from each.
The first is people who are anti-corruption professionals, such as certified fraud examiners, because they deal on a daily basis with situations in which there's serious wrongdoing. They have a lot of knowledge. Their professional body does a lot research. They understand the prevalence of corruption, the impact of it, and how it can be exposed. For example, they will explain to you how research demonstrates that whistle-blowing is the number one strategy you need to avoid and expose wrongdoing. It's much more effective than anything else.
You need to speak to former PSIC clients. These are whistle-blowers who have been through the system. You've heard some names here. We've suggested three different people here.
