"Hmm I thought 200 was hundreds .......... could be wrong though."
A blond moment perhaps?

The minimum value of hundreds would be 2 in order to give a plurality.

For those not thoroughly bored by the recent discussion, to have a requirement to carry ID does not automatically mean it will be asked for. The vetting is far more stringent for travelling by air than by ferry. Also car drivers can be identified by their registration.
If I can google any UK car registration and determine if it is taxed tested and insured, I am sure security forces can go much much further in among all those computerised data banks where our electronic alter ego/doppleganger exists, and the average person would be astonished to find out just how comprehensive these records are. Linking NI number to passport, to driving license, to bank details, to vehicle details, enables electronic tracking on a scale never dreamed of. Couple this with phone and internet surveillance, vehicle tracking, even to monitoring oyster card individual movements in London. Additionally, DNA and fingerprints are routinely hoovered up, despite breaching article 8 of the right to respect for private and family life.
Big Brother has arrived with a vengeance and is being kitted out with all the latest bells and whistles. With a few keystrokes, those that wish to, could generate a more accurate profile of you than you could generate yourself.
Perhaps the argument should move on to how we allowed the state to be privy to all our secrets, and what dangers it presents to a democracy? Cant vouch for the accuracy of the links but they give an idea of the road we are on.
