I really like De Becker's material. Oddly enough the one SD book I have that has been written by a woman (Beauty bites Beast) feels the most gung ho and almost dismissive of some of the issues he raises. I find it difficult to read as it comes across as a very 'angry' anti-male text. Were you referring to my book list or course list, as I feel my course list does address the concerns in that thread - but that is of course with the bias that I know what I want to cover under each subject heading and how I want to weight it. I spend far more time on 'friend/relative/carer' danger while on the subject of violence and sexual crimes than I do on stranger danger. Most of my book list is concerned with attack patterns and psychology and physiology relating to stress and danger rather than physical techniques. My main source of data on violent and sexual offences comes from government, police and ED papers rather than books.
