The best lesson of all is to realize just how important ethics is. All of this publicity has really raised the profile of ethics; three years ago, no one really knew what ethics meant. Now, people can see how ethics rules apply to public servants, ministers and members of Parliament. It's important to give ethics the importance it deserves by underscoring its role.
As I said earlier, if there is a problem with the act, amend it; do not look for loopholes. That is what's dangerous. That is how credibility is undermined and how people lose the confidence they normally have in the system.
