A man whose wife has just announced that their marriage is over, that she is leaving and taking his 3 beloved children with her. This man, a normally decent individual, is boiling with rage, frustration, humiliation and loss. His life as he sees it is over - pointless. His anger immense.
Don't know if it applies in this case but, having gone through a divorce with children, many of us can certainly relate. And, as a pilot, anyone that goes to a shrink for help needs to have his head examined because then you lose your medical and you are really angry.
It is an avenue that certainly should be investigated in the human factors aspect of the investigation.
I would imagine that the visiting FBI agents will tread very gingerly on the scrutiny of a community activist with Muslim origins as portrayed in media accounts due to political considerations at home and in Malaysia.
