Thought this might be interesting - about the protection (or lack of) available in the law:

If the thieves say 'oops they didn't realise those boulders with pictures on they were winching away were worth $1,000, or of any archaeological value' then they get away with it.
However in this case, the defendants got convicted of stealing government property. Which isn't really enough.
The usual thing about knowing the price of everything and the value of nothing I suppose.
What protection do stone things have in this country? Or is it just *gold* the law's interested in?
