LOL. It all depends on who's going to stop them. CSI: Graveyard? I don't think people care that much about corpses. Ethically, I think it would be fine to take the deads' organs, and would make the living feel better, if they didn't specifically mention that they'd prefer not to be disemboweled. Otherwise, it's not like the dead are going to care. It's more of a concern of the currently living/not dead yet (but we can always lie to them..).
edit: so yeah, basically i agree with the doctor ppls in the article
