Rhubarb have you actually read that met police link? It has little to do with this conversation. It stems from a study about domestic murder cases, and involves cases that have come to the attention of the police.
In the opening it says this: "This analysis is based on incidents reported to the Metropolitan Police Service. However, the lessons learnt are relevant to all those working within the field domestic violence and to the criminal justice system as a whole."
We have established that most rapes are not reported to the police. Further, not all rapes are committed by partners and not all rapes have attendant violence (aside from the act of rape obviously).
The report is looking at a subsection of very violent domestic abusers who have rape as an an abuse in their repertoire. Again, many many women experience rapes outside these circumstances. The study is interesting in as far as it goes... but that's it.
Also, why are you asking everyone to read stuff. But when information is posted about things that does not fit with your way of thinking, you dismiss it.
