Gov placed containers everywhere. Cities were blocked down ( something that has never happened and we had Zia martial law). Did you seriously expect them to go back home and sit and drink tea. With the containers removed PTI has no reason to attack its own caravan and seriously in such incidents the outfall is outward not inward.
If they wanted to create anarchy they would have attacked back and created a situation but they didnt. PTI showed massive restraint for a caravan of 100,000 people. They took the attack even attacks to their leader and didnt answer back. If imran khan wanted anarchy he would have told his supporters to bash everybody's skulls in and many would have been dead by now but that is not the result. Thus its not imran khan as an opportunity was missed to create anarchy bcz he didnt want to create anarchy.
One can again use model town incident and point out that qadri told his supporters to attack the police and many policemen were injured and killed. That is anarchy. Can you say the same happened here?
