I can see him doing the right thing only if his hand is forced with legal action. Honestly, I think even now that he knows, with your appearance at trial and through certified letters from those who sent them, that shareholders are watching, he would still try to stiff us, maybe by offering enough for us to break even (which I would consider a loss after having my money tied up for 5 years), or maybe even a bit less.
I'm not sure what Carter's IQ is; I'm sure he's not stupid, but he is greedy and arrogant.
