Asiah Bibi was not easy target, probably was behind the bars or in police custody. Salman Taseer was easy target for mumtaz because law enforcement trusted mumtaz to provide security to Taseer. You are talking about courts as if you are unaware of how things goes in Pakistan. I can say same about mumtaz, if he had any problem with Taseer's words, he could go to the courts. What Salman Taseer did was his opinions and not very Pakistani me and you need to agree with him, but what mumtaz did was a crime far greater than Taseer's. He set a trend, killed a human and betrayed his job.
Those acts maybe against "aspirations" of majority, but majority never ask you to go on a killing spree. Pakistan doesn't need enemies when people living in Pakistan have self destruction mentality. Neither taseer's comments nor PMLN "declarations" demand answer from few terrorists and chaotic anarchit mullas. While you are the first ones to criticize India if they kill someone who slaughter a cow (which they consider their God) but you are intolerant and ready to kill someone who says something about Blasphemy law? Why hypocrisy and double standards? It should be same rule for everyone, rite? If by your logic majority have might so they should have right. I personally believe Blasphemy Law should be amended to make it more transparent, as of rite now any mulla can declare someone with whom they have personal beef, as blasphemous and courts are ready to sentence death penalty, if somehow they escape from being sentenced by courts then mentally ill public will execute the penalty themselves.
Because they are scared of mullas, so are majority Muslims. A normal Pakistani folk only care about roti, kapra, makaan.
