IH must resolve this seeming contradiction.
They are under no obligation to resolve anything, except to their stockholders.
Either IH knew the scam was underway or they did not know the scam was underway.
I believe they did not know the scam was underway at first but they later realized it was. Why do you think they had to know one way or another the entire time? That makes no sense. Why would they pay $11 million if they knew it was a scam?
For that matter, how can you judge any of this? You have no information on any of these tests. For no apparent reason, you seem to be convinced that the one-year test was legitimate. You seem to trust Rossi's word on this, even though he has told you nothing at all about the test. If you knew anything about it I suppose you would agree it was a farce.
