The reports of her being cognizant were from doctors willing to lie for the Schindler's. The state's selected physician declared her in a PVS. And again, since you didn't answer ... why keep her alive in that condition? It wasn't about her parents. It wasn't about their needs or inability to let go. It was about Terri. How long would you want someone to keep you in that condition?
Oh please. Lol. I don't think the doctors would lie about a patient's medical condition and risk their entire livelihoods and careers. That is just . . . ridiculous.
And yet, there was no risk to either. So much for your strawman.
Of course there is! Doctors cannot lie about a patient's condition. That goes against their oath.
First of all, there's nothing in the Hippocratic oath about lying. But even if there was, the oath is not legally binding and no [legal] consequences stem from violating it. That's not to say there aren't legal risks for other malpractices which may or may not break their oath, but that would be an appearance of coincidence and due to the malpractice violation, not breaking the Hippocratic oath.
And as it happened, the Schindlers' physicians lied about her condition, which was ultimately proven she truly was in an irreversible persistent vegetative state, and no consequences befell them. Most notibly, because a diagnosis to some degree, is based on opinion. But such opinions can be bought, as the Schindler's did.
