Harry's name was brought into it, it seems, because Survival International brought the atroticiies to the attention of Prince Harry in his role as president of African Parks. They clearly believed he would intervene and help, it appears Harry quickly got rid of the hot potato, bounced it back to the CEO and washed his hands off it.
Harry calls himself a humanitarian, while he may not have a fiscal or admin accountability (although I believe he does) he certainly should have a moral responsibility and accountability not only in his role as a member of African Parks board, but in his role as a humanitarian and a human.
A whole year has passed since Harry was advised, he could have used his position to highlight the atrocities being carried out by employees of African Parks and support Survival International and the indigenous community by publicising what was going on , maybe taking a leaf from his friend Oprah during the sexual abuse scandal at her S. African girls school.
Not much of a humanitarian when it comes to it.
