Can anyone avoid CCTV surveillance? We ask an expert

The hit BBC thriller The Capture has thrown the scale of camera surveillance into the spotlight. I ask Gus Hosein, director of Privacy International, just how advanced the technology is – and if it's possible to avoid it. You've got to watch The Capture, Gus. It's about a police officer who finds people hacking into the CCTV network, and it hit home how omnipresent cameras are. It started with stadiums and transport, because of football hooliganism, and was later expanded by Tony Blair as a solution to crime.
