This might sound dumb.. but couldn't terri's mom hold some water in her mouth..just a little bit to moisten terri's mouth?
If Terri were not trapped in a death camp, under normal circumstances one would be able to do as you say.
The guards are under orders not to allow this.
Terri has to die, and they are going to make sure she does.
No. Judge Greer has issued orders that she cannot have ANYTHING by mouth. Breathtaking...
