I believe they have already started an investigation: http://www.bloomberg.com/news/2014-02-26/bitcoin-holders-resigned-to-losses-as-mt-gox-faces-japan-probe.html

So even if that mtgox recovery strategy document was fake, do we believe the numbers of their defecit being 750k bitcoins? It's all over the major news headlines, but I have yet to see any credible sources.

Also, re: the confirmation that the document was true: That report was done by fox news, the news organization with possibly the least credibility of any in the US. Furthermore, Kerpeles did not confirm the authenticity of the document. On the contrary, he flat out denied it. Quoth fox news:
"In the IRC obtained by FOX Business, Karpeles denies the document was produced by Mt. Gox, but confirms that it is “more or less” legitimate. "

Note that the only thing in quotes is "more or less", not even the whole phrase "more or less legitimate". Which means it was probably taken completely out of context in classic fox style. So not only are we getting goxed, we are getting "foxed'.

Can anyone find a source claiming gox owes 750k btc which cites any source other than the two bit idiot?
