If indeed it happened, the smear campaign against McCabe was a 'flop'
Two key Garda witnesses - Sergeant Maurice McCabe and Superintendent Dave Taylor - have potentially explosive stories to tell.
The version of events from each of them has a common thread - but there are also some important differences in their evidence upon which this major inquiry into our police force now turns.
Supt Taylor will today begin his third tough day in the witness box at Dublin Castle after already facing nine hours of straight questions and then cross-examination on Monday and yesterday. The man who headed the Garda press office from July 2012 until June 2014, has spent his time telling the Disclosures Tribunal how he tried to "ruin" Ireland's most notorious Garda whistleblower, Sgt McCabe.
