Very quickly, I think it's a problem of culture. It was mentioned by my colleagues.
For too long, Canadian governments have not developed the culture of security to warn the general population or elected officials of the temptations or danger that they will be facing. If you have access to power, you become a target. You are somebody who might be approached and used. Intentionally or unintentionally, consciously or unconsciously, you will be used.
Let's remember one thing. The Chinese wrote the book 2,000 years ago: The Art of War by Sun Tzu. It's right there, how to use influence. They know exactly how, and they're really, really good at it. They've become even better, so we have to develop a new culture.
