Don't know if you saw the interview, but think you are being very harsh in calling the bereaved son a "moron."
He did not specifically put the responsibility at the feet of the governor. He asked the question as to why the men were sent into the mine despite the history of roof failures.
There might be good, valid answers to his question, but does it really seem moronic to you to pose it in the first place? If it was your family member who had died, wouldn't you want answers?
After the fact, yes.
