This is rather apples to oranges. Blue collar manufacturing work where women run at only 25% of the workforce and men have higher than national average crime rates --- you are bound to have more problems with the men. Not to endorse the author's view, but compare the above to your typical white collar environment with a more even distribution of men and women doing similar, non-physical work. Easier to judge the gender differences there.
