This convention underpins Peter Taylor's episodes from Irish Republican and Islamist terrorism, for his Talking to Terrorists is "not an autobiography but the story of a journey". Taylor has dealt with Irish Republican terrorism since the late 1960s, and earlier published a trilogy about the main actors in that conflict. His television documentaries may not be "art", in the sense that Adam Curtis's Power of Nightmares BBC series was "art", but the workmanlike Taylor is honest enough to recognise that the threat from terrorism is real, and not a conspiracy against our civil liberties.
