As a former UPenn student, I found this book to be especially horrifying. The U.S. tried the Nazi doctors for their crimes against humanity, but then we decided that the Nurembug Code didn't apply to us. Instead, the human medical experiments that went on at Holmesburg prison, which are described in disturbing detail in Hornblum's excellent book, were not unusual in this country. I liked this book because it exposes the hypocrisy beneath much of American morality. Out of one side of our mouth we quite rightly condemn the Nazis for their grotesque acts, but then we turn around & sanction similar experiments on disadvantaged members of our own population. Perhaps the most interesting section of the book is its history of medical experimentation in our country, which began well before the second World War & continued until the mid 1970's. A must-read.
