Another thing is in figuring out whether males really are more violent than females.

If you take the percentages of males to females who are imprisoned for violent offences then this might not be the best measure of violence for a number of reasons. Some of them include:

- Males tend to be stronger than females and hence if a women has a violent outburst she is less likely to harm (and hence less likely to be prosecuted)
- Women might be over-represented in psychiatric wards and under-represented in jail (there has been much written on how females with BPD are likely to present for psychiatric assistance whereas males with BPD are likely to present before the courts)
- Women might be smarter (with respect to avoiding detection for their violent crimes)
(unlikely but possible) ;-)
