Sorry, I know there are other threads about this but I have just been shown the Daily Fail's latest bit of 'reporting' on this.
They have dug up the fact that the boy's father had a drug dealing conviction a decade ago. This is pointed out in a huge headline. About 100 lines later, in tiny print, they note that since then he had been college, held down a normal job, married and had a family. For a DECADE!
They have stalked his Facebook account and say that all the photos are of his wife, kids and work.
They have interviewed a load of randoms blaming the parents and insisting that they categorically KNEW the gorilla would not hurt the boy. 
That poor family... For all I know they could be neglectful parents but nothing I have seen or read provides any evidence of this. They were looking after a baby and for all it seems were distracted when the 4 year old fell. I have 3 kids and could easily see how this could happen.
I can't help wondering how different the reaction would have been if it was the child of a middle class white couple ( and I say that as someone who is middle class and white).
I really feel for them. Their little boy will probably be completely traumatised long after he has physically recovered. The whole family will probably suffer as a result of his previous conviction being made public.
