Independent of how this turns out for Terri...I don't want the state, church or the courts involved in my (or my spouse's) end-of-life decisions.
Sorry, but the state has right and responsibility to stop people from murdering other people -- even if it's your wife who proposes to murder you, or your husband who wants to do it. Terri's is not an "end of life situation," as you put it -- unless her husband is allowed to end her life. She won't die - unless he's permitted to withhold food and water from her. It's no more an "end of life" situation, than yours is right now. IF somebody is pointing a gun at you, it's an "end of life situatino" if he pulls the trigger - - but if he doesn't, you'll go on living. Same with Terri. And just as government can tell the gunman not to shoot you, it can tell Terri's husband not to kill Terri.
