To refer again to the famous letter dated 24 October 2015, he was quite vociferous in his attacks on Mr. Barrett. That is quite unusual. Whatever someone might say behind a person's back, to put it in writing and nail this guy in the manner that he did when he said Mr. Barrett "just stopped short of calling a deputy commissioner a liar" and when he referred to his "irrational behaviour" and "lack of respect" was quite something.

It was quite damning language that he used in respect of Mr. Barrett.
