Surely Bhatti was assassinated not because he was Xtian but because he was proposing (rightly)the reform of Pakistan's blasphemy laws and also (and also rightly) the pardon of the Xtian woman sentenced to death for blaspheming the prophet after a row in the agricultural fields with some rather fundamentalist women.

If I am right he was assassinated not for what he was but for what he said.

I would however be surprised if these Vatican figures were right.
