Medical experiments

After about sixty years, medical experiments conducted on unknowing Guatemalans by the USA were revealed by professor Susan M. Reverby. This included deliberately infecting hundreds of people with sexually transmitted diseases, and have by Guatemalan President Alvaro Colom been described as a crime against humanity. We are still waiting for more than apologies. Questions also arise if/where/when other similar experments have occured? Full accountability is very important for such tragedies not to be repeated.
