Polis has taken to the battlefield with three talks by journalists back from the frontline: A multi-media man who has been shot in the course of his work for the Guardian and others; a top TV camera journalist who runs his own production company and has made films for the likes of Newsnight as well as a documentary feature out next year; and an Iraqi who has worked through the recent war and now trains a new generation of journalists.
