It's not. Families sometime border on delusion when they are in denial concerning a suicide. They want it to be an accident or something else. If there were any doubt (such as in this case), they would be scrambling for answers.
"It may be that -- in some circumstances where matters have not been so thoroughly investigated as in the situation here -- there is an enhanced public interest in knowing how a public servant died."
What's this guy been smoking? Thoroughly investigated? That's what the whole lawsuit is about. It hasn't been thoroughly investigated and what has has pointed toward murder. Unbelievable.
