While the photo itself may well be genuine, commonsense shows that, contrary to what the caption suggests, this photo couldn't have been taken at Kincora, as Kincora was a small guest house type building.
So has someone being trying to blacken Heath's name by associating him with notorious boys' home Kincora, some of whose ex-staff were convicted of child abuse?
