At the NTI - a rather high end event - there were three psychologists with PhDs and one PhD anthropologist. Two were college professors. I gave a talk to all those practitioners about the psychology aspects of legal gun use.
You may remember that the major progun professional books in the literature were written by PhDs in universities. Kleck, Lott, Jacobs, Kohn, Oyster, Stange and some others I don't recall now. Currently there is an article in Chronicle of Higher Education debunking some of the antigun hysteria from VTech.
Jan Libourel has a PhD in history from Oxford.
DCougar - didn't mean to insult your paper. Also, I was responding to some of the other slams on PhDs. I had to laugh as I wrote as a first paper in English a strong anticommunist paper. I got an 'F' - however, my writing was crappy.
