It's a bit late telling us now, Mr McGuinness
Why now? More pertinently, why not before? Why is John McGuinness, former chairman of the Public Accounts Committee (PAC), coming out now and telling the nation that former Garda Commissioner Martin Callinan tried to undermine the credibility of garda whistleblower St Maurice McCabe?
It was wrong of the Commissioner and it was symptomatic of garda management's attitude to whistleblowers. No question about that.
However, why did Mr McGuinness not reveal it when the Dáil committee was probing the issues raised by Sgt McCabe? Why not inform the other elected members of the PAC?
