Well first, you'd have to hire FELOS, to get to SENATOR KING, to get the law changed to ALLOW FOR DEATH BY STRANGULATION, while the patient is in a HOSPITAL UNABLE TO SPEAK OR TALK.
Because, right now, DEATH BY STRANGULATION IS A FELONY.
At the time Terri could talk, DEATH BY WITHHOLDING FOOD AND WATER, VIA A TUBE, WAS A FELONY.
Michael Schiavo hired Felos when Terri couldn't speak her wishes, got the LAW CHANGED so HE COULD WITHHOLD FOOD AND WATER FROM TERRI SO HE COULD KILL HER.
Even today, death by withholding food and water by mouth still is a felony.
