If he is an independent investigator, why would he advise someone he is investigating about whom he or she should speak to? What is the Department's view on an independent investigator telling people what they should or should not say if asked a question? I am asking about Dr. Thorn. The committee received a letter from Mr. Ó Foghlú today. It states:

Given that the investigation is underway it will be important to ensure that nothing is said at the Committee hearing that would compromise the investigation. The investigator, Richard Thorn, has also requested the Committee be advised of the need to avoid discussion that would potentially do so.

Does the witnesses have a letter from Dr. Thorn asking them to tell us this?
