At central issue here is what she wanted. The preponderance of the evidence suggests she had no wish to be killed. However the courts simply took the word of a husband, and obstinately refused to review any other evidence on the matter.
Again and again, year after year, they reiterated the original finding without any review of its veracity.
At this point it might be a little embarrassing and unsettling for people who advocated her death to still care about the truth. Some might even feel enough secret guilt that claim its a "witch-hunt" -- an absurd exageration worthy of Senator Durbin. That aside, there is good reason to review the case in the light of improving the law regarding such determinations.
The court saw all the evidence; you haven't. The court ruled that there was clear and convincing evidence that Terri did not wish to live under those circumstances. This ruling was upheld at every level of the state and federal judiciary.
