Robert Herring sounds like a great guy. But while it might annoy MS to have to turn down 1 m illion dollars, he most likely would look at his turning down of the money as "proof" he's only trying to fulfill his wife's wishes to any who doubt this. And he probably figures he'll get much more than 1 million for the rights to his "inspiring true story" if and when he succeeds in bringing about terri's death. In that respect, I can see this backfiring : "He turned down 1 million ! What more proof do you need that he's just trying to see his wife's wishes are carried out? obviously he's not motivated by greed."
You nailed it, IMO. He can't possibly accept.
