Given the importance of Scalia and the ramifications of his death, an autopsy and toxicology report should be required. What would it hurt? It hurts no one unless someone who has something to hide.
He was a 79 year old man and there was nothing suspicious about his passing. I’m sorry if you think the government should have the authority to mutilate his remains to satisfy your curiosity, but I prefer to respect the wishes of his family.
