"Describing herself as part storyteller and part whistleblower, Koller said she is exposing the truth in hopes of preventing future failures,".  Koller provides HER interpertation of events and not just the info from the documents.  And preventing future failures will continue as long as failures are blamed on systems, departments, city, state, government, etc. and never on the people responsible.  So who were the individuals responsible who failed to protect Peter Boy and what disiplinary actions were taken?  As usual no one is held accountable.
