While I would definitely not celebrate the death of the Pakistanis, Pakistanis, or at least a significant portion of them, by virtue of their behaviour, are on the verge of inviting punitive actions, such as, but not limited to, being declared personae non grata in civilized societies.
These trouble makers might be minority, but the extent of their violence, lack of respect for the law of the adopted land, and the silence of the majority, or their incapacity to control their own kind, surely places the entire community in a very bad light. There is sympathy for those that are indeed civilized, and there is a point of exhaustion of this sympathy.
It's time for introspection.
