I just do not see how keeping quiet about it has done any good. The perpetrators of violence use this one a lot mostly because it's true.
Nothing gets a man in a homicidal mood better than alcohol.
Growing up in an environment where abuse of women is seen as normal also helps immensely. This behavior is generally passed down from one generation to the next. Just as the woman's behavior of meek, compliant victim can be learned from watching her abused mother. From my experience, I estimate about 90 percent of violent crime is fueled by alcohol. It's probably a little less than that nationwide, but Wyoming is a hard-drinking state and that's where my knowledge lies.
