The blockade of news channels by cable operators is a very condemnable act. But the PPP government has maintained throughout that it is not behind closure of news channels. There is, though, the strange coincidence that whenever any big scandal related to President Asif Ali Zardari (who is also a co-chairman of PPP) comes in media, the channels suffer blockades. If we assume the government is not lying about its involvement in closing of channels, why is it not able to investigate who is behind this mysterious action? The government, it seems, has no interest in finding the answer to this types of questions. -MUBASHIR MAHMOOD, Karachi, August 12.
