Consult a lawyer. If you are in the USA it should be possible to find one that will give a free consult. I know a couple I could ask, PM me if you want. I think the big question will be how you came by the info. If you found a box full of paper in your parent's basement, the problems may will reside with whoever took the notes. If you stole it out of the KH, you're in trouble.
I agree, it would really make a case against how the WTBS does things.
