Just watched the last episode of Power of Nightmares too. As a bit of a sceptic about the threat of terrorism and the war against it, I didn't think it would tell me much I didn't already know. I was very wrong. If anyone is ever brave enough to release it in the US, I recommend everyone watch it with an open mind.

Remember when all the politicians were tellin g about the devastation that would be caused if terrorists got a hold of nuclear material and made a dirty bomb? Well did you know that if you were in the vicinity of a dirty bomb and weren't actually injured by the blast, then it would probably have no effect on your health, or maybe would raise your risk of getting cancer by 1%. You raise your risk more when you sit in a smoky pub.

And remember all those arrests of people who were supposedly al-qaida terrorists in the UK and US. What percentage do you think were convicted of or even charged with planning terrorist attacks?
