I must thank you for putting this here.  It is the truth.  He represents the largest number of families that lost loved ones.  Questioning the story and seeking real answers and not propaganda is considered by some to be the most respectful thing those who lost someone can do.  Thats probably why almost half of the families are still looking for answers.  They realize that no plausible answers were given. And no it's not just about letting go, that serves as an excuse for many.
