We are calling on the US State Department to raise our free speech concerns for Rafael and all citizens to the Angola government.Rafael goes on trial March 24th on politically motivated charges relating to a book he wrote in 2011 alleging human rights violations in the diamond industry by generals in the Angolan military and private businesses. He also filed a criminal complaint against those alleged to be responsible for the abuses described in his book, seeking justice for the victims of the country’s diamond industry. As a result, Mr. Marques was formally charged with criminal defamation; prosecuted for simply exercising his right to freedom of expression.
