Someone I know well was working for Oxfam in Haiti at the time of the scandal. She knew the man at the centre of the allegations fairly well.
Yes, there was use of prostitutes - of whom there were plenty who wanted the money. Even before the earthquake unemployment was apparently running at 60%. The fact that prostitution was technically illegal in Haiti, did not mean that it was not rife.
But as was well known by those who were there, the use of prostitutes was going on to some extent in every NGO, including the other big names. Someone my source knew well, who was working for another big name NGO, complained to her management that male staff sharing her accommodation were bringing prostitutes back.
The response was, ‘Find alternative accommodation, then.’
But there was not a word about that NGO in the press.
For some reason, although it was always well known in the sector that staff were using prostitutes (not illegal in so many countries) Oxfam was singled out for ‘special treatment’. It was presumably political, and at least partly IMO down to the ‘holier than thou’ image Oxfam had liked to present over the years.
