I'd like to agree with Plasmahead2 but I think the truth is the home owner is a victim of circumstance and the contractor didn't know it was toxic either.
How ever maybe some one like a buyer failed to check into the product deep enough. They seen a chance to make a fast buck and pounced on it.
That's the American way yea? Or the Whole wide world way I guess.
I mean its just Gypsum and paper right? What could go wrong? You think any of it got into any China mans home or businesses? They would probably execute any one who complained so we will never know.
