"Law enforcement approaches to violence against women MAY deter some acts of violence in the short term. However, as an overall strategy for ending violence, criminalization has not worked. In fact, the overall impact of mandatory arrests laws for domestic violence have led to decreases in the number of battered women who kill their partners in self-defense, but they have not led to a decrease in the number of batterers who kill their partners. Thus, the law protects batterers more than it protects survivors."
I don't know the details of 'mandatory arrest laws' in the US and don't have time to research it just now. I'm irritated at how much more easily i'm finding analysis/critiques of US domestic abuse legislation as opposed to stuff from over here. I really want to know what impact the new legislation in the UK has had - and whether it's keeping men safer over and above keeping women safer!
