May I ask what both Imran Khan and Qadri are up to. So far, what is it that they have accomplished, besides disrupting law and order, creating chaos and increasing our difficulties?The government has shown extreme restraint. If I had any authority, I would have cordoned off the ‘dharnas’, not allowed anybody to come in or go out. As it is, most of the people, including Imran Khan, go away during the day, relax at comfortable places, eat and drink and come back in the evenings to create a lot of noise. This is absolutely belligerent behaviour, and somebody must put an end to the madness.DR ZAHEER ASGHAR KHAN, Lahore, August 28.
