When I first heard about Shahbaz Bhatti's assassination, there seemed to be nothing sensible to be said about it. Not yet another prediction about Pakistan's growing instability, nor even an outpouring of anger of the kind that followed the killing of Punjab governor Salman Taseer in the English-language media. The assassination of the Minorities Minister did not appear to portend anything beyond the actual tragedy of his death. And nor could anyone say it came as a surprise. A loss of words, then. A painful punctuation mark.
