Well, the dharna is a shaming tactic.
Dr. Qadri probably didn't count on how little shame his opponents really have. In a country with a democratic and egalitarian political culture, a leader would feel too ashamed to remain in office -- on the basis of blatantly rigged elections, and while lieing about having a mandate -- when faced with protests like that.
Our elected politicians could not care less about anything pother than money and privilege.
They could not care less about actually doing the right thing.
After this dharna, I am sure they are now even more despicable and loathsome to people than ever before.
So there probably needs to be more violence to bring down corruption-mafia politicians like this.
I'm not advocating violence; realistically, though, a mere 3 days of violence out of 68 will not put enough pressure on criminals.
Dr. Qadri will continue to order his people to be peaceful; I am not sure whether they will obey, though.
