Again, you're asking me to speculate. I can speculate that they may have wanted to avoid being held accountable or being identified.
We've had quite an issue in Toronto. I'll explain this as quickly as I can. When I issued an order that we would wear name tags, a number of concerns were raised by our police union. If people were identified by their name tags, they could then be subject to harassment through the Internet--they could be identified. We actually went before an arbitrator, and we've been awaiting a ruling for over two and a half years. But they expressed an apprehension that if they were identified by name, persons could identify them, locate their addresses, and perhaps subject them to threats and things. So that is one possibility.
