No, it wasn't. And had Terri's father not managed to smuggle in a video camera and shoot some footage of Terri, her case wouldn't have been contested this vigorously either, and Michael et al. probably would have gotten about $500,000 from the trust fund.
I see no reason that Michael would have believed, in 1997, that he would have to spend over $500,000 of "Terri's" money in legal fees to get his wife killed. Thus, I see no reason to believe that money could not have motivated the Schiavos' testimony about Terri's supposed "wishes".
No reason?
His feud with her parents began in 1993 when they demanded half of his $400K loss of consortium award -- that should have given him one good reason to think there'd be a rough road ahead.
"Thus, I see no reason to believe that money could not have motivated the Schiavos' testimony about Terri's supposed "wishes"."
As I said before, without further proof of conspiracy I'm going with "possible", not "plausible". Just not enough there, supercat.
