This is very interesting stuff.

On a side note, how would you measure the motivations of a rapist? - How would you ever find out what motivates them?...

Well, you could conduct some science. I have some experience in trying to scientifically account for human behaviour - it's usually very difficult to do.

In any case, a case series I just read suggested that "rape is more a sexual crime than a violent or power crime" sample size was only 61 - food for thought though.
