I think this post, “AAA Ethics Code Changes,” which deals with anthropological ethics especially in connection with the Human Terrain System and in other applied settings, is excellent for being very direct, concise, and gets straight to all of the most important points in the critical analysis of the Human Terrain System and its threats to local hosts, anthropologists themselves, and to these things we call the anthropology profession and discipline. The author is a recent graduate from a B.A. program in anthropology, somebody who obviously understood the essence of much of what we do.
Bonus points: yes, imperialism really does make you a dick.
To see what how an elite college fails to teach the basic lessons of how not to treat people as servants, pawns, and targets, see this post, and this other one. The claim in the latter piece is that students were not shielded from the ethical issues that arise from HTS (that’s grand), but in the meantime were exposed to its chief recruiter and PR stunt person.
