What would prevent the Schindlers from turning around and suing Michael Schaivo once they got guardianship? He'd turn down this offer on that basis alone. This sounds like yet another Allred publicity stunt.
All this hopeless gesture does is win him fans for refusing the money.
I'm sure the Schindlers would be more than willing to sign a unconditional release of any potential claims to sue him in exchange for him releasing guardianship and divorcing/annulling his marriage to Terri. I just don't believe he has any good will left in him to allow him to do the right thing.
