I think there is no problem to give Army a role in the matters of Government like ISI is not under ministry of interiors,
you can give Ministry of interior at all to the Army, some retired general be the minister and on duty personels work and run the ministry's affairs, which should control all Law enforcement in Pakistan if you are not able to shut down the attacks made by insurgents and failed to protect your people, not more than this we have experimented a lot.( bombig looting banks mobile snatching bathha khori target killings have become a usual phenomenon in Pakistan apart from Taliban factor ) you have given a lot of room to your enemies to work on. This role must be given by the parliment to Army sort of an additional work to train and groom the national law enforcemnt agencies and made them as disciplined as our Army is. I am asking for this when I am hearing about different models about Pakitan, this will be constituional and rewarding also. Do think on this line that army are spcialized for fighting and defending so their role must be specialized in politics if whatsoever. They shouldnt be regarded good in negotiations, running schools and hospitals, respoding to the strikes made by civilians. They will always consider strikes as challenging writ not as a right.
