Kate, I have been over on the Frank Hamer article, in between working on Tours and Charles Martel, and the Mongol Empire Series, (just rewrote Berke's stub into an article)  - which have really turned into great articles.  On Hamer, I took out the word "murder" altogether referencing the ambush, and have simply stated that increasingly historians question the legality of the ambush.  This is documented, and true.  I have tried to follow your example in simply stating facts, in an encyclopedic manner, and allowing people to draw their own conclusions.  When you get time, see if you approve of the revisions, and thanks!
