That is lame, and behavior unbecoming PTI. I hope this was the act/words of an individual, and remains so. All through the years, PTI has been criticizing MQM for halting public life when something untoward happens in Karachi. It would be a shame for PTI to do the same.
But I dont agree with the assertion that this shows the reality of PTI as a party. PTI has had more rallies/processions/jalsas in the past 2-3 years than any other party, and none of them has affected public life or property in a negative way. I expect the trend to continue.
