After Terri passes away, which she most likely will because no one wanted a confrontation, I would charge Schiavo, Felos and Greer with conspiracy to commit murder. They conspired, and succeeded, to change the laws to kill Terri...
That will never happen. To do so would be to admit that they did nothing while it happened.
Florida law allows people to be starved to death under certain circumstances. That this is so, I find quite offensive. Whether Terri qualifies for this execution is a separate question.
That MS would press forward with killing Terri, in spite of her parents wishes, is just plain cruel.
