I don't think it shows support to al queda to claim that they didn't kill her. They want the world to know they killed her. They claim responsibility with pride, so the best thing you can do to piss off al queda is to undermine there accomplishment and not give them credit, all the while intellegence agencies are trying to solve the case and catch those responsible, also they may have lied to keep the culprits from an early flee, but this is less likely since al queda almost imediatley claimed that they did it. I think it's pakaistans way of saying "f" you to the al queda...I could be wrong but that's what it sounds like to me.
