When you plunder a grave for whatever reason you're going against the wishes of the deceased and of those who put him/her there in the first place. Some would say that the situation changes once we reach a point in time when nobody who personally remembers the deceased is still above ground. That's probably where I'd stand in this.
Bob, I guess I spoke too soon in my previous post, but I can see that you share some of the sentiment, at least regarding the acknowledgement of past beliefs. This is essential when dealing with past civilizations--an understanding as to who these people were.
This gets back to the overall conundrum, because the Catch-22 signifies that to learn more about these people, one would have to study them closely, and in order to do that . . . It seems to go around in circles. Can their ever be a solution to satisfy all sides?
