Thousands of Automatic Number Plate Recognition cameras are already operating on Britain's roads.
Police forces across England, Wales and Scotland will soon be able to share the information on one central computer.
...Kent's Chief Constable, Michael Fuller, commented: "We've seen an increase of some 40% of arrests since we've been using this technology.
"I'm very confident that we're using it properly and responsibly, and that innocent people have nothing to fear from the way we use it."
Don't believe him? Well, just read this testimonial by an innocent person who had nothing to fear:
John Catt found himself on the wrong side of the ANPR system. He regularly attends anti-war demonstrations outside a factory in Brighton, his home town.You're living in the country which gave the world George Orwell. That country looks a lot like the USA should be about ten years from now.
It was at one of these protests that Sussex police put a "marker" on his car. That meant he was added to a "hotlist".
This is a system meant for criminals but John Catt has not been convicted of anything and on a trip to London, the pensioner found himself pulled over by an anti-terror unit.
"I was threatened under the Terrorist Act. I had to answer every question they put to me, and if there were any questions I would refuse to answer, I would be arrested. I thought to myself, what kind of world are we living in?"
