 Professor Alan Dershowitz, an American legal scholar and columnist for the "Huffington Post", has attacked Amnesty International's perceived bias against Israel, claiming that AI absolves Palestinian men of responsibility for domestic violence and places the blame on Israel instead and that it illegitimately characterises legal acts of Israeli self-defence as war-crimes.Dershowitz has joined NGO Monitor's calls for an independent evaluation of anti-Israeli bias within the organisation.In 2004, NGO Monitor, a pro-Israel organization, released a study comparing Amnesty International's response to the twenty years of ethnic, religious and racial violence in Sudan – in which (at that time) 2,000,000 people were killed and 4,000,000 people displaced – to their treatment of Israel.
