Wendy McIlroy attacks VAWA 2005. There is more info here.
VAWA has received $5B of funding over the past 10 years, and I wonder if there are any studies showing that any of the money has done any good. I suspect that the money has done much more harm than good.
Here is a 1998 study with domestic violence statistics. It shows that one can do a survey asking for complaints, and get complaints. But it fails to show that the VAWA approach helps anything.
