Maybe they'll do a funeral once it's announced.
hard to prove death when there is no body.
Also no way to prove those graves have a body or that they are who they say it is.
Remember the mix up around the grave stones at Arlington when POTUS went there on the Day to remember those who gave their lives?
Another few potential grave mix-ups
"Oswald"
someone got a court order to open his grave to make sure the alleged body was there.
"McCursed"
Real ID body was left behind somewhere and they didn't send it back to US [citing expense] in the early 70's [ there's the documentation in past breads but can't find it at the moment. ]
