> it could relieve a great deal of pain and suffering
I confess I don't understand this. The families know how their loved ones died, when, and sort of where (in the ocean). How does knowing the precise location help any?
I think the rituals around death aren't complete without a story. It's the reason why before they tore down the eastern span of the Bay Bridge that let the families of people that died on the bridge visit the spot where they died.
I understand wanting to know more details. But having gone through rituals around death of someone close myself, it doesn't ease any of the pain.
I've also wondered about those families attending the execution of the person who murdered their loved one. I doubt it eases their pain and suffering in the slightest.
