Some suggested reading, not that you will want to as you seem pretty biased.
The New Zealand Report From New Zealand, The Manga Report from Ontario Canada done by government to check into benefits of Chiropractic, and the Wilks et al court case against the American Medical Profession for Anti trust practices against Chiropractors. This will get you started but there is more if you want it. It is not your profession that I am questioning but your bias to other health professionals and there obvious results.
