Don't blame the Pakistan govt alone.
What about the relations of the victims agreeing to accept blood money and then pushing off to the US, if the report is true?
the compensation is not in the form of US citizenship, its only in the form of money, the passports must be handed to them by back door meetings, passport is just a bribe, the compensation money is done in faith to give relief to the poor families having lost the bread earner in return for forgiving the killer
this also shows islam is a reliion of forgiveness and not of revenge those who throw garbage on islam and islamic laws
