Sir: Now even teachers can be assaulted openly. Students of National College, Karachi manhandled the principal when he tried to stop them from cheating during an examination. There are two parts to this horrific incident; one is the molestation of the teacher by students, and the other, the demand of the students to be allowed cheating. What is happening to our society? Is there anyone out there to check the abnormal changes taking place in our moral structure? TASNEEM ZAHID Karachi
