Wasn't there a post in which (Roger Ver?) supposedly examined Mt. Gox's books only a couple of months ago and even he wanted to buy insider Mt. Gox bitcoin at a slight discount? Please correct me if I'm wrong, but he is very well respected so perhaps he was shown fake balance records?
He made a video last summer after Mt Gox started having problems with USD withdrawals stating that the reason for the delays in the withdrawals was not due to a lack of money in the bank accounts.
