Not wanting to acknowledge the failures of any organization to meet even its own standards due to human frailty of its membership extends across every organization that I have ever been a member of, read about, watched as an observer or in any manner been aware of.

Political parties, governments, educational institutions, corporations, sports organizations, police, churches, non-profit clubs, news organizations; there is no organization created by fallible human beings which does not experience failures ... and then tries to hide those failures from others for many reasons; some noble;  some base.

No one wants to acknowledge "feet of clay".  

It's human nature.
