Hello NickCT  Could you please describe where synthesis is occurring  that is, can you show where the article is "combining material from multiple sources to reach or imply a conclusion not explicitly stated by any of the sources"? Could you please describe what you think is a violation of WP:POV? WP:COATRACK is an essay, not a policy, so COATRACK issues are a matter of personal opinion, not of policy.
A few points regarding deletion:
 There are several books, journal articles, chapters of bioethics textbooks, etc. that have been written specifically on the topic of this article (unethical, nonconsensual, and/or illegal medical experiments in the U.S.). They clearly separate this topic from that of human subject research in the United States in general.
 There exist articles for several other nations that are similar to this one, such as Nazi human experimentation, North Korean human experimentation, Japanese human experimentation. They exist for the same reason that this one should exist  numerous high-quality reliable sources have identified these topics as worthy of study in themselves.
 A wide array of reliable sources have identified this article's topic as worthy of standing alone as an object of analysis, separate from the broader history of human subject research in general. Per WP:NOTABLE that means that the topic of this article is worth of its own article. Just because many of the experiments in this article are things that most people would consider "bad" (which is why most medical ethics textbooks generally use them as illustrations of "bad science") does not mean that it is "biased" to have an article on them. WP:NPOV does not say that articles can't be about "bad things". It says that we should neutrally report what reliable sources have to say about things, regardless of our moral/ethical views on them. This article neutrally reports what medical ethics texts, and histories of this topic have to say about it. I am not aware of anywhere in the article where it is not neutrally reporting what reliable sources are saying. 
That said, like all articles, this article is an incomplete work in progress, so there are certainly issues. Rather than merely citing policy without reference to this article, please make specific suggestions for how to improve this article.
