For example, in many countries, domestic violence has only recently been recognized as a crime. In other countries, it is considered to be outside the state's jurisdiction ... Mertus further documents that "in Brazil, until 1991 wife killings were considered to be noncriminal "honor killings'; in just one year, nearly eight hundred husbands killed their wives. Similarly, in Colombia, until 1980, a husband legally could kill his wife for committing adultery."
Best to do up a 4 page post and innumerable media articles on all those Christian South Americans too.
Seriously, whether this case is an honour killing or not that is directly related to Islam (which is unlikely, as this sort of thing is rare in places like Malaysia), directly related to local custom (possible) or just a case of a fucked up family and father (perhaps the most likely scenario), it is interesting to note how such practices occur today in some Latin American countries, in African nations (both Christian and Muslim). It wasn't that long ago (and I mean within my lifetime) that such things occured in Italy and Greece, too.
The point being that family violence is an issue a lot larger than one of "well, it's a Muslim problem".
