If I were her parents, I would do it!
No, It isn't obvious. These parents have gone through so much, they are not about to jeopardize their position now.
Michael wants us to think that's what they did, but he doesn't even let them visit her without someone present. He is the one who goes behind closed doors. A nurse has already testified she believes he injected Terri with something a few years back.
Felos also said that after the parents' visit, Terri Schiavo was found in "a disheveled state" with her feeding tube wrapped around her back and a medical wrist band pulled up very tight on her arm like a tourniquet.
I think he carried it too far by staging the feeding tube and allergy band. Terri's parents would not have left her in that state. It sounds like a staged job to me.
