David Walsh has long pursued the Lance Armstrong doping story as sports writer for the Sunday Times.
He has said he hoped Armstrong would, "go to the World Anti-Doping Agency and provide a detailed account of the way doping operated in cycling from his point of view, because he was such a key figure for so long."
Lance Armstrong cannot expect to be redeemed after his brief TV confession. Names must be named.
Tyler Hamilton, a former team-mate of Lance Armstrong who implicated him in the doping scandal, has told ITV News, "I'm proud of him".
The self-flagellation makes for gripping television but it does not really amount to much in the long run.
