Ubiquitous,
You say “He isn’t in a coma, he is dead”. Is that your p’sak? Because this site is marginally defined as Jewish, thus for you to make such a declaration, you would have to have a legitimate basis.
You also say, “It is the law of the land,” Specifically what law are you referring to? I have never heard or reads of a law that says a hospital must take someone off life support (at least in the US before all provisions of Obamacare are effective)
