There are definitely two schools of thought on the pervasive use of surveillance cameras. In some cities they've been credited with reducing crime and fear of crime and they played a crucial role in the London bombing investigation. But then there's the Big Brother thing. Some people think the negative impact on privacy outweighs the benefit. Others ask why any law-abiding person would be concerned about cameras in public.

If you're not doing anything wrong, what is there to be worried about?

That's exactly the question the Houston Police Chief asked when people in that town objected to his plan to place video cameras around town. To make their point, privacy advocates are turning the camera on Chief Hurtt, offering a reward to anyone who can capture an image of him committing a crime, "any crime."

Interesting. I don't think it will take long. Most people can break several laws just walking down the street, which of course is the point.
