Matt Y (and AS) miss an important line from John Burn's reporting, as have most of the media, including CNN:
The documents leave uncertain the degree of involvement by Bhutto, a Harvard graduate whose rise to power in 1988 made her the first woman to lead a Muslim country. But they trace the pervasive role of her husband, Asif Zardari, who turned his marriage to Bhutto into a source of virtually unchallengeable power.
I don't know that Benazir is blameless, but I'd lay even odds that it was her husband at the center of most of it. He was the one known as "Mr. ten percent".
It may also matter quite a deal, in terms of religious law, who owns what. I'm not sure that applies, but it is also something that many commentators gloss over.
