US Medical Experiments on Guatamalan Peasants in the 1940s

Here is a really horrific story about American medical experiments on Guatemalan prisoners, soldiers and mental patients in the 1940s. From 1946 to 1948, the United States government "paid for syphilis-infected Guatemalan prostitutes to have sex with prisoners. When some of the men failed to become infected through sex, the bacteria were poured into scrapes made on the penises or faces, or even injected by spinal puncture." The details are gruesome, and what is particularly upsetting about this is that it is taking place as the Nuremberg trials are getting underway. So at the very same time as the United States is decrying the crimes of Nazi physicians, the United States government was itself sponsoring medical research that was clearly in violation of human rights standards.
