I would like to call attention to the last of the excerpts from Are Prisons Obsolete? that I just posted, in which medical experiments performed on American prisoners between World War II and 1974 are glancingly described.
Medical experiments on captive populations. If you, like me, are a recovering liberal and still in the back of your mind keeping a list of things the U.S. hasn't done recently that make us* in some way better than the Nazis, you can cross that one off.
*"Us" in the sense of "me and a group of people that may or may not include some of the people I'm speaking to." I wish English could distinguish between "me and you" us and "me and them" us.
