I know we are the most watched nation in the world here in the UK,it will only be a matter of time untill some bright spark of a lawyer will use this.
In the UK, you believe that the more information people have about you, the safer you are. Whenever you step out of doors in the Greater London area, you are almost certainly being photographed and can be tracked if necessary.
In the USA, we have not been able to progress beyond more ancient concepts of civil liberty (which are concepts we have in common with the UK), chiefly because (1)about 1/2 the US population is so conservative you wouldn't believe it, and (2)we do not have any way to properly regulate any abuses of civil liberties.
On paper, there are statutes in the United Kingdom that would scare the hell out of civil libertarians in the United States.
But our system is different. You have a huge and powerful civil service in the UK. Sir Gus O'Donnell shadows everything the Prime Minister does, and in The Queen's name he can find out whatever he wants any time that he wants it. It is the civil service, for example, that heads up your Joint Intelligence Committee, not the politicians.
It is different here. There's no BODY, no Crown, no civil service that would stand in the way of a runaway government, and in the USA people are permanently paranoid about it.
It is a problem. As we experience first hand that we need more and more information in order to make the people safe, we are going to have to find a way to make the people feel safe about who is collecting the information, how it is being done, and why.
