Re: Pmln to setup military courts in Sindh
You cannot compare situation in Karachi with situation in FATA. If there is any problem in Karachi then it is problem of law and order, similar to law and order problem all around Punjab and interior Sindh. Here, no one is trying to replace government writ with their writ over the area. It is duty of civil institutions like police to handle law and order problems and civil courts to deal with determining and punishing crimes. Government cannot bring army to handle law and order by disbanding courts and starting military courts. If government cannot handle situation with police than government can take limited help from army, still there can be no justification of bypassing civil courts and establishing military courts in the area, as that is effectively martial law. If any government would ever do that at one place then it would be invitation for the people of that area to get alienated feeling themselves as being occupied people and thus struggle for independence from occupation (what happened in Bengal). Thus, if such situation arises that government has to use military courts in civilian matters even at one place than it is better, for sake of country, that government resigns and let army rule the country directly.
As for FATA, problem is of insurgency and rebellion, where armed groups (Taliban, etc) are trying to establish their influence on Pakistani soil using arms and want to enforce their own version of law and order in that area. In effect, these groups are challenging and wanting to replace writ of Pakistan with their own writ. If Pakistan keeps quite and leave them to impose their writ (law and order) on Pakistani areas then it means Pakistan surrendering those area to these insurgents or rebels, something no government can afford. If government cannot subjugate these insurgents or rebels using police force, than to establish writ of Pakistan and reclaim any area Pakistan lost to these insurgents or rebels, Pakistan has to use armed forces and if necessary can also use military courts in these areas bypassing civil courts.
