Interesting to see the story of who he was but did not go into enough detail on the crimes he committed. Lots of allusion and the odd light hearted question but no real interrogatory questions. A better documentary would be to investigate the people who surrounded him and who enabled him to do what he did. For the length of time he was allegedly active, someone must have known what he was doing. The BBC, hospitals, morgues, police forces, VIPs and royalty - someone knew!
