I have finally accessed the link providing info on laws on euthanasia in Florida. You can follow the links through for specifics.

Don't feel bad about not knowing everything about Terri's case. It is so huge and involved that ALL the facts on it may never be known.
As you stated in your post, and I agree, it makes no difference (but for the legal aspects) what her condition is. She's a living human being and should not be regarded as a 'useless eater' who deserves only to be eliminated.
If Terri did not want to live, she wouldn't have survived so many attempts to snuff out her life.
Personally, I don't think anything but a miracle would put her in a recovered state. I do think proper treatment and therapy could provide improvement in her condition, if this latest deprivation hasn't harmed her irreparably. Even if that is the case, you don't kill her.
Thanks for taking the trouble to find the link.
