Sir, I would again give you an example of the US political system. Which like the world has its own issues and many serious ones. For example, today, the top Republican leadership made clear statements that if a Democrat is elected President, there will not be any movement on the Supreme Court justice appointments throughout the next 4 year (Republicans control the House / Senate). Now what do you call it? This is a total personal issue resulting in reducing the Justice systems ability to provide speedy justice and technically, is a violation of the American constitution that we all cherish, as the Justice and Safety is a State's MAIN responsibility.
Now do you expect the Democrats (assume they get elected) to now shut down the DC metro or go take their voters and shut down NYC or do violence there? HELL NO!! The ONLY course of action they would have, is to go back to the legal system and try to push these appointments. If they can't they will make it a known issue to the public in the next elections and will let the people decide. That is it. No matter how "wrong" a political issue is or anything, you can never initiate violence, destruction of public property or damage to a country. In the US and many other countries, (knowing some law due to my background), it comes under treason and will be severely dealt with by the respective justice system. Pakistan, India or China are no exceptions to it.
Mr. Khan needs to realize, if he didn't get justice from the court system, the people (majority) don't want his version of the truth and they want to continue to vote the "other side", well, unless Mr. Khan can get majority, he has to wait. He can't initiate violence, public unrest, and damage to a running city or its public. In fact, this is probably a punishable violation of his own oath that he took when he got elected. Thanks.
