Recent government proposals to allow increased police and intelligence agencies' monitoring of email and social media communications have angered civil liberties campaigners who claim they are a breach civil liberties.
A new report by the think-tank Demos examines "the ethical, legal and operational challenges involved in using social media for intelligence and insight purposes". Co-authored by former GCHQ director and ex-cabinet office security and intelligence chief Sir David Omand, it argues that police and intelligence agencies need to use social media as a form of intelligence but that laws need to ensure a balance is struck between security and intelligence work in this new environment.
Join us as we discuss to what extent security services should be able to monitor our cyber activity. Is this form of cyber surveillance a threat to the public's civil liberties or necessary to keep them safe? Can a balance be struck?
