if greater interest of the country is involve, agencies do held people under interrogation until the whole case reaches to end. some time it takes years to unearth complete gang.still agencies r also answerable to law and SC is also responsible for basic human rights of people of Pakistan,so agencies should satisfy the courts by showing or producing evidence for their detention so that it is justified.our media and all other pillers of state should keep in mind that security of Pakistan is supreme and they should not corner the agencies. in USA how many were detained in Goanta namo bay and for how long? did their courts or media and human right organizations made hue and cry for a specific time gap? why because it was in the greater interest of their people and country.so plz trust ur prestigious agencies and do not start pointing a finger towards them. after all what ever they r doing is in the greater interest of Pakistan and its people.
