This is not exact science. Terri was neither "clinically dead" nor "just...disabled." The term "severely brain damaged" would fit as well as any.
Of course we'll never know now what the outcome would be, but Terri had fluid on her brain that was never removed and should have been. If her rehab money had been spent where the jury intended, the fluid would have been removed
and nurses and rehab would have continued. The rehab money was never used as intended and the courts are to blame for that.
