Since when Amal Clooney has become an authority on human rights?

How did she become an authority on human rights? Was that during her stint as advisor to Bahrain tyrant? Or was it when she advised the Hariri family on the Hariri court? Or was it when she worked on Israeli and her husband's project for the creation of the war criminal state of South Sudan? Or was it when she turned down the offer to investigate Israeli war crimes in Gaza?
