If you didn't believe that Orwell's 1984 was inexorably becoming a reality you should read this:

BBC NEWS | England | Kent | Local groups discuss terror signs:

Neighbourhood Watch co-ordinators across Canterbury have been finding out how they can prevent terrorism.
It was one of the main issues discussed at an annual conference held at the Kent city's Christ Church University.

Co-ordinators were told how to spot signs of bomb-making and other preparations for terrorist acts.

What an awful prospect. If this is even necessary, which I frankly doubt, the best way to be watchful in our own communities is to be better communities, to know and if possible be friends with your neighbours. Neighbourhood Watch is a worthy campaign, and best placed to spot strangers coming in to burgle our homes and so on. But to spy on the very neighbourhoods they are set up to serve? No thanks.
