Really, I'm not sure why the resistance to changing the law is so prominent. You actually have some real recourse here, at the ballot box - you have the power to fix this situation by electing legislators who will change the law in ways you find more acceptable, for guardianship and end-of-life issues. Take hold of the power and exercise it, for God's sake. For Terri's sake.
If you happened to catch Hannity and Colmes last night, Catherine Crier was promoting her book, cowritten with another lawyer (maybe a judge), a man of great sense...can't recall his name. Anyway, Catherine went ballistic about this case, said it was all political, that the judicial branch was under attack, that they'd done the right thing denying Terri food and water, etc. She looked as if her head was going to explode because the other lawyer kept making sensible points, such as the fact that activist judges terrified of what's coming down the road were asserting power over congress and the president. He insisted what they'd done was unconstitutional.
