Sir: Terrorism and street crime are the oldest problems of Karachi. It was horrible to learn that two policemen were caught who were involved in kidnapping. Moreover it is worth mentioning here that often people who are responsible for providing security are themselves the biggest threat to it. The police definitely deserve respect in society but due to some black sheep the entire police force is defamed. Those who were involved deserve severe punishments that can be marked in history so that none will ever try to think of getting involved in such crime again. SHAEMA SAHER Karachi
