The point is that Judiciary doesn't have the executive powers. Judicial activism is born when administration become inactive. We always trust conspiracy theories and word of mouth more than underlying reality. Even with perfect co-ordination among the agencies and LEAs, when there exists a terrorist organization committed to her cause, a breach here and there would always be expected. This is because terrorists live within us, have support from within us...So while a foreigner will always be susceptible to being identified and monitored easily, it is not possible when locals are operating against the locals. Can CJ's ruling to stop terrorism stop this menace? Answer is a plain No. Secondly these groups operate freely because they have breathing space and No go areas where they train and breed with impunity. Plus of course the ample amount of funding being channeled to them both externally and internally. And of course the violence of Karachi which carries a mix of ethnic,sectarian and political content has become a plague. Unless we don't address these issues, we will keep collecting bodies every now and then. My dear friend Judiciary is a watchdog, not an executioner.
Here is a very nice analysis by Najam Sethi sb. Especially his analysis of anti-insurgency policy dynamics between India and Pakistan.
