The statistics of CCTV (Thanks, John!)
The borough of Wandsworth has the highest number of CCTV cameras in London, with just under four cameras per 1,000 people. Its total number of cameras - 1,113 - is more than the police departments of Boston [USA], Johannesburg and Dublin City Council combined.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
