McGuinness should have spoken sooner - or not at all
Many people will understandably be appalled by John McGuinness agreeing to a secret meeting in a hotel car park with then Garda Commissioner Martin Callinan.
I agree the prospect of the meeting does not look great. Here was a parliamentarian leading a process of scrutiny into the operations of An Garda Síochána who agreed to meet the force's most senior officer.
But against that, there was a chance Mr Callinan could have had some information to impart which could have impacted on the work in hand. Politics and public life is sometimes strange - there was also a chance that what Mr Callinan had to say could not really have been done in any other way.
