© the UK is now one of the top three surveillance states in the world, third only to China and Russia. I saw a preview of David Bond's new film, Erasing David, last week. It's being shown on More 4 next Tuesday and explores privacy, surveillance and the information that is held about us all in the UK on public and private databases. In the discussion following the screening, David Bond got asked about whether surveillance was necessary to protect our safety and keep us secure.

He suggested that only the minimum information necessary should be collected and stored, but one of the keys to us all feeling safe comes from knowing our neighbours and feeling part of the community. So, if you want to get involved in your local community, just add your name to TimeBank's database of over 250,000 people interested in volunteering (and if you're worried about what we do with your data you can check out our privacy policy).
