I think there's no smoke without fire. Just too many people coming forward about the same thing. Why would Wade Robson make this up, particularly as he's not poor and he's a very minor celebrity?
There were reports (TMZ possibly? I cant remember but I bet I4U can find it.
) that he lost a lot of money recently. Even so, he is far from destitute.
There were also suggestions that he has been paid to make the claims to discredit Jackson because of the current trial.
