"The list is long. It will take at least dozens of pages just to describe the criminal past of the PFI leadership. The point is -- most of the PFI leaders have a dark past filled with hate for the country and its establishments. All they want is the implementation of their own ideology at any cost. They have no concern for the common Muslims," a source said.
