I'm still thinking about your previous question. I want to distinguish between two kinds of surveillance, private and public surveillance.
When I go into a bank and it has cameras, I'm on its property, and it, in using those cameras, has legitimate use and would have to specify, of course, some of the questions Professor Bennett was concerned about: who gets to see it and how long it stays.
The public area concerns me a great deal, because there is endless talk about putting more video cameras in downtown areas of cities. Vancouver is talking about this endlessly. Leading up to the Olympics, we're going to have security issues. They're talking about putting them on Granville Street, the major north-south street in the city. The question here is, has this been sufficiently understood? Is there a cost-benefit analysis? Of course they have to prepare a cost- benefit analysis for the privacy commissioner of the province.
