This year’s BBC Reith lectures came to a close today with the last of three lectures on Securing Freedom, presented by Eliza Manningham-Buller. The name may mean nothing to you but she was the Director-General of Britain’s Security Service, aka MI5, between October 2002 and April 2007, and she reflects on 9/11, the wars in the Middle East and how the world has changed in the last ten years.

The three lectures are titled, “Terror“, “Security” and “Freedom” and a give a British perspective on the role of the intelligence services and the relationship with the US during a period both countries were under attack. If you are a seasoned spook-watcher, there’s probably not that much new, but I personally found it revealing and reassuring that the British Security Service is more measured and ethically-minded than the media would have us believe.

Baroness Manningham-Buller doesn’t shy away from controversy either, steadfastly refusing to accept torture as an intelligence tool, and suggesting that the US’ use of waterboarding was a “profound mistake”. You’ll have to listen to the podcasts to understand her reasoning.

The lectures are available as podcasts and also as transcripts for those who would prefer to read.
