Mixed message from US government for victims of unethical medical research

From 1946 to 1948, American and Guatemalan physicians infected prostitutes and prisoners with syphilis without their knowledge or consent in order to test penicillin. The research was discovered by a Wellesley College professor in 2009, and lawyers for the victims filed a class-action lawsuit against the United States.  The Obama administration claims that the US is immune from such lawsuits, but has announced that it will spend $1 million to review new rules to protect medical research volunteers, $775,000 to fight sexually transmitted diseases in Guatemala, and will develop a system to compensate anyone harmed in medical research.  Lawyers for the Guatemalan victims say that the promised action is inconsistent with the claim of immunity.
