I like Melissa Lee, but it was a dumb question: "Can you guarantee that there is no fraud in the Chinese Reverse Merger companies?" He gave exactly the right answer (and what I expected) ... "I can't guarantee there's no fraud in the American Reverse Merger companies either!" (both paraphrased from my memory of the interview.)
This boils down to do you trust the auditor as much as anything for any of these companies ... do they do their job with diligence the way they're supposed to. Do they have a tract record?
