Its an old joke I heard that well, archeology is just defacing/looting some old tombs. If you mess up and go for a tomb that is too fresh, you will be in trouble.
But that raises a good point: When does defacing/looting a tomb becomes archeology?
Like when we open the tombs of old pharaohs, that is considered archeology, but try to open the tomb of old popes or the old kings of England and I'm pretty sure that will be considered as defacing a tomb.
So is there a demarcation between when you deface a tomb and when its considered ok because is archeology? Like a number of years since the death, or is it really just on a case by case scenario (like, for instance, if the empire is still active its probably gonna be frowned upon)?
