Molly Ball talked to opponents and wrote a piece about it:.

I do not condone the opposition by sharing this except:

"The act's grants have encouraged states to implement "mandatory-arrest" policies, under which police responding to domestic-violence calls are required to make an arrest... But Villegas and other critics say mandatory-arrest laws can backfire. A 2007 study found that states with such laws saw increases in intimate-partner homicides -- perhaps because they made victims, who may have wanted the police to intervene without making an arrest, less likely to report abuse before it could escalate out of control. "

@CallMeDave I wonder if the stats are true. I need to look at that.

@Bierbasstard Agreed!

@PalacinkyPDX Absolutely! That is one of the reasons women are killed at higher rate than man. Should not happen!
