It is an accepted rule that one has to listen and obey to every lawful order given by a policeman. But the problem is who will decide if it is a lawful order or not. Our citizens and even the police are ignorant of the legal rules and regulations governing the country. The law of the land for the citizens is decided by the police officials patrolling our streets. The police take undue advantage of the ignorance of the people, regarding legal understanding. There have been numerous cases where police has transgressed their legal authority and have used unlawful means to carry out their duties. HASSAN BASHIR, Islamabad, March 25.
