I write to you as a concerned citizen, who feels greatly upset and ashamed at learning that a Karachi University professor was brutally beaten by the Rangers - supposedly appointed as the law keepers and safety providers at the University. One would like to ask the following questions from the authorities; what business do Rangers have of administering law and order at the highest seat of learning? What role does a VC have in controlling the Rangers who control the university? Can a VC protect his professors from being beaten up by his own Rangers? -NAEEM SADIQ, Karachi, via e-mail, April 4.
