If I agree with you for a moment then Pakistan has been doing it since beginning and it is not working. In Balochistan it has been utter failure, Bangladesh is still asking for a bloody apology after we lost it, tribal areas have become hell and no Pakistan can even go there, this strategy has been failed in Karachi, in Afghanistan our dream of strategic depth is taking last breaths.. this is creating more ruffians! Every country has it's own ground realities,.. since all these measures have proven to be more fatal what is wrong in think some other way out? Law is there if it is properly investigated. We need to empower civil rule and give such technology and tracking mechanism so that criminals are not escaped easily. We still rely on the muharar to write a freakin FIR. This is the basic problem and solution.
New law is already enacted which is called Protection of Pakistan Ordinance! It is pathetic hope against hope that situation will change as this nation has already seen plenty of ordinances, executive orders, banning the organizations but that resulted in more drastic problems.
You are free to think whatever you like. I have made my point clear.
