Point me to the photos that were taken by the secret service or other legal entity. Oh wait none of that was done.
As far as I can tell, the Secret Service does not provide security to members of the SCOTUS and would have no jurisdiction here.

And who is to say that photos were not taken? But why should such photos be made public? Let's say my elderly uncle who had a history of heart problems and not necessarily known for following doctor's orders and taking care of himself, was found dead in his bed, with no signs of foul play - should the LEO's take photos before removing the body, should that be made public?
I think too many people get their ideas about forensics from TV shows like CSI (especially CSI) and Law & Order and all their variations. In 60 minutes, less time for commercials, everything is neatly tied up and the forensics people on these shows always find the most obscure cause of death and it's never a "natural death" because there would be no drama in that. But the real world doesn't work like a CSI type TV show.
An autopsy just isn't required or necessary for all deaths.
He was nearly 80 years old, overweight, a smoker and a drinker (and at his age and with his medical issues, even being a moderate or "social" drinker would be risky) and according to his own private doctor who spoke with the officials in TX and with his immediate family, he had HBP and a history of heart problems and was determined not to be in good enough health to undergo surgery for a recent shoulder injury.
To believe that there was a cover up of a murder, one would have to also believe that all the LEO's, the police and I am assuming at least one EMT, and the funeral home director - all would have to be "in" on the "cover up" not to mention Scalia's own family, his wife, children and grandchildren who did not want an autopsy performed.
