What is the truth about domestic violence?

The Daily Beast has an article by Philip W. Cook titled In Cases of Domestic Violence, Men Are Also Victims (H/T Dr. Helen). Cook explains that despite the perception crafted by domestic violence advocacy groups, women commit domestic violence as often if not more often than men:

Straus and his colleagues found that in minor violence, the incident rates were equal for men and women. In cases of severe violence, more men were victimized than women, with 1.8 million women victims of severe violence and 2 million male victims of severe violence a year. Women suffer a greater amount of total injuries ranging from mild to serious, but when it comes to serious injuries where weapons and object use come into play, the injury rate may be about the same.

Hundreds of scientific studies support what every experienced law-enforcement officer knows: half the time, it is a case of mutual combat; a quarter of the time only the woman is violent; a quarter of the time only the man is.
