I don't know Mr Moody, and I wasn't there, but if the facts are as reported, the phrase "isn't life a little bit too short ....." comes to mind.
Regardless of his contribution in the past, if he can't cope with a simple explanation of the facts, I'm pretty sure aviation would be a better place if he stayed on the flight deck of his whizz bang jet.
Please don't forget that if someone makes a complaint to the CAA, they have a duty to follow it up, and that if Mr Moody did contact individual SRG officers, it's highly likely that they would not have been aware of that he'd been previously talking to colleagues.
