Also I understand where you coming from, and also I kinda agree with providing data to solve things we like to solve, including crime.

All positive has its negative sides as well. More surveillance is less privacy. When used only for the good, then nothing wrong. However, when used for the bad, then everything is wrong. The danger is that we take small steps allowing forces to invade our privacy more and more for good reasons, to eg prevent some crime; But after taking many of those small steps, we will come to a point of no return and we only need a couple of bad actors to abuse the power one has when being able to track individuals in society. Somewhere we need to draw some lines and I think we need to draw it between voluntary and obligatory. Today, providing camera footage to the police is on voluntary bases, the police union likes this to be obligatory. Did you read the book 'The Circle' by Dave Eggers? A different approach to big brother as George Orwell took, one of voluntary transparency by wearing a camera as a third eye; The book shows in what this can turn into, something nobody wants.
