In the kabuki theatre of British parliamentary politics, great crimes do not happen and criminals go free. It is theatre after all; the pirouettes matter, not actions taken at remove in distance and culture from their consequences. It is a secure arrangement guarded by cast and critics alike. The farewell speech of one of the most artful, Tony Blair, had “a sense of moral conviction running through it”, effused the television presenter Jon Snow, as if Blair’s appeal to Kabuki devotees was mystical. That he was a war criminal was irrelevant.
