By the way I am sorry you have had to go through this. I have too, and I've felt most emotions avialable in the human repertoire. I'll tell you though, there's more than a glimmer of hope in this situation (sans the death warrant).
Basically, I am pro life and against the death penalty. I do not think government has those rights to exercise.
Therefore, I believe those rights to be with the family, and to be a family decision as they are the ones who bear the responsibility and the burden thereof.
Unfortunately, this family is so severely spit that the courts got involved. This is always a mistake.
