First, Mr. Chair, as I said, I will not comment on any investigations. However, in answer to the question that was put to me, I will state on the record that there have indeed been cases, a number of them, in which during the performance of our investigative work we have come across people who have had information that was relevant to our investigation and have simply refused to talk to us. That has happened more than once, including for matters of some significance.
On April 1st, 2014. See this statement in context.
