It's truly hard to comprehend how horrible this is:
From 1946 to 1948, American public health doctors deliberately infected nearly 700 Guatemalans — prison inmates, mental patients and soldiers — with venereal diseases> in what was meant as an effort to test the effectiveness of penicillin.
American tax dollars, through the National Institutes of Health, even paid for syphilis-infected prostitutes to sleep with prisoners, since Guatemalan prisons allowed such visits. When the prostitutes did not succeed in infecting the men, some prisoners had the bacteria poured onto scrapes made on their penises, faces or arms, and in some cases it was injected by spinal puncture.
Here's why this post was given its title:
In a twist to the revelation, the public health doctor who led the experiment, John C. Cutler, would later have an important role in the Tuskegee study in which black American men with syphilis were deliberately left untreated for decades. Late in his own life, Dr. Cutler continued to defend the Tuskegee work.
Am I being a bit over the top? Perhaps, but consent should be obtained from any individual undergoing a medical experiment and such consent should be informed. If Dr. Cutler was afraid that he would not be able to obtain consent, perhaps he should have conducted the expirements on himself or his colleagues - with their informed consent.
