As Scotland Yard confirmed the use of cameras didn't lower the crime rate.
In fact people were blaming the unchanged crime rate to the fact that the physical deterrent of having cops parole areas may have actually positively influence a decline in the rate of crime.

The question remains why? If the presence of CCTV hasn't done anything then isn't it questionable that a fortune is spent on what appears to be no more than Governmental voyeurism?
It doesn't add up, and had you mentioned not so long ago that there will be a day that to every 14 people there is a camera and that for a simple trip to the convinience store will have you captured on tape up to 300 times would have seem far fetched.
How about if I said there will be a day that the Government will have mandatory microchip inserted under your skins to monitor you're every move, slowly but surely chipping away at your freedom at your personal privacy, a threat to even your will.
Would you still be surprised? In light of what's happened?
What if they're laying down the foundation for a day when Martial Laws will be implemented and having us all micro chipped helps control you if riots break out against systems already in order.
Not a lot of people know about the Northern Union pact which was signed by Bush WITHOUT the permission of the American people, thus merging Canada and Mexico as one super state and ultimately neutralizing the constitution and everything that makes America the free country it is.

So do you really still think the CCTV cameras are about burkas?
