Who killed Bhutto?

Or is that even the important question?

Instead, who is it best to blame? As always, our old friends.

I am extremely curious to see what happens in the next few weeks. Musharraf seems to be hoping that by blaming al Qaeda he will be able to minimize the unrest from Bhutto supporters. Perhaps even solidify his rule and/or extend emergency powers so as to deal with the now (as he would like it to seem) obvious danger of Islamist extremists in Pakistan's nether regions.

Will Pakistan believe it? For myself, as little as I know, I can't imagine that Musharraf would have had her killed. It would invite massive amounts of risk and would especially alienate the more conservative, staid and very powerful elements in the army who seem to value stability above all.

What happens if Pakistan believes it? Do they support Musharraf and view his attempts to maintain power more leniently? Does the election continue?

What happens if they don't believe it? Chaos. Obviously. But how much? Enough to stop the election? Some opposition parties have already announced that they will boycott the elections.
What happens if the elections break down? Does everything go? And what will emerge from it?

Update

Interesting viewing from al Jazeera.
