Karachi is burning in the flames of ethnicity and sectarian killings. Every politician worth the name comes only for a press conference and claims that he knows who the real culprits are? Some even mentions a figure of 150 culprits. What I do not understand is that if they know the number, their names and their location, then why dont they arrest them? What is it that they are scared of? The country is disintegrating piece by piece. Are these so-called patriot politicians waiting for the doomsday? Are they waiting for the oracle of Delphi to unmask these criminals, who have crippled the country and held hostage the population of Karachi? To tell you the truth, I believe that they are all making it a source of political point scoring. But let me tell them in the same manner, that once they have lost the country, they would lose everything. AMJAD H. MIRZA, Lahore, October 21.
