Zeuhl, I think it has to. Kids raised in the west will eventually rebel against against antiquated attitudes and barbaric practices - and against repression - as this poor girl did.
I was cautious because I know that brothers, sisters and cousins are often implicated in these outrageous cases but hopefully without the lead from the older generation they will be able to adjust their thinking.
So they WERE both born in rural Pakistan. So why aren't they deported as undesirables? Send them back to their birthplace and see if they survive in their own 'loved community.'
My opinion of these evil people, although the crime was committed here they should be deported & do their sentence where the orig came from & their house given to their family.
