The Middle East Quarterly just published a timely article by Ms. Phyllis Chesler about the differences between dishonor killings and domestic violence. The article contains some interesting charts of cases in North America and Europe, though I can tell by eyeballing them that she's missed some of the cases (i.e., the charts aren't necessarily comprehensive).
I don't necessarily agree with all she's written, but I commend her for using data and copious documentation to make her case. That is what I attempted to do in Reclaiming Honor in Jordan, and it's an approach that needs to be used more often. Too much of what is said and written about these crimes is emotional, illogical, irrational, and/or not based on empirical evidence or hard facts. And that is impeding progress rather than contributing to it.
Here is the link to Ms. Chesler's article, "Are Honor Killings Simply Domestic Violence?":
