The death of Benazir Bhutto is tragic, yes. But it was also absolutely a predictable event. I am convinced that Musharraf himself made every effort to protect Bhutto, but ever since she arrived in Pakistan after the U.S.-brokered deal for her return and rejected the government security efforts, the efforts to assassinate her were inevitably going to succeed. Her insistence on relying on her own greenhorn security forces, and speaking to her supporters in the old way - the large rallies, the public demonstrations - were decisions that doomed her to martyrdom. There is a point where courage becomes recklessness, and Bhutto was far beyond that point.
Talk that Musharraf was a tacit supporter of this assassination is balderdash in my mind - he was never one who wanted Bhutto dead, nor the political pressure that will come with it. The man has stuck his neck out for American interests on more than one occasion, he's now taken off his uniform, he was willing to participate in a negotiated power-sharing alliance - and in return, he was blasted for announcing a crackdown and state of emergency that, in retrospect, was more than deserved.
It is a sad day for freedom and democracy in Pakistan and around the world - but a predictable one.
