Sir: It is most deplorable that members of one of the most peaceful communities of Pakistan are killed with impunity by the Lashkar-e-Jhangvi. Do our intelligence agencies not know the whereabouts of this group? Are they ignorant, indifferent, and or plain incompetent? Whatever the case may be, it is unacceptable. I suggest that the civil society of Pakistan file a petition in the Supreme Court to take notice of this matter. KAUSAR SK Karachi
