There is no reason to do a test if you already know the result. Unless the test was to proove that she was not in pvs then why do it? In court, the Schindlers even admitted under oath that they knew Terri was in pvs. So what is the test for those of us like you who if the result is different than what you want will just ignore it and point to as another part of the conspiracy.
Tests are often rerun. New tests are often done. Especially if time has passed since the old test.
Emotions still linger from Nancy Cruzan’s right-to-die case
Sheriff Doug Seneker guarded [Nancy] Cruzan's room at the Missouri Rehabilitation Center. Lawrence County Sheriff Doug Seneker was a deputy sheriff at the time. He questions whether Nancy Cruzan was in a persistent vegetative state. His opinion is based, in part, on her reactions three days before her death when he went into her room to check on her."[Nancy Cruzan] turned and looked at me and stared at me with a panicky look, sweating profusely, and the thought I had was, she was thinking, ‘Oh, here’s a policeman, he’ll help me.’ But we weren’t allowed to do that,” said Seneker.
Before the law was changed so that PVS was a death sentence, why should the parents have cared what the doctors called Terri's condition? Given that the term PVS had historically been used to apply to people for whom signs of cognition had not been confirmed even though they might exist, why should the parents have objected to such a diagnosis?
