I believe Hawass is in jail due to the new peaceful government.
not. It sounds like you are confuing the fact that he was *charged* with selling antiquities with the idea that he was arrested, tried, convicted and jailed. None of the latter events occurred.
He has been cleared of all charges, and actually holds a government post as Minister of State for Antiquities.
