The Law v What's Right?

Two articles to read on the lawsuit by the 9/11 families versus members of the Saudi Royal family.

One here, and one here.

It's obvious which way one's heart might go. But what about the law? The second link to NRO suggests the law isn't actually clear. The Obama DOJ has sided with the Saudis. I'm not certain Bush would be doing anything differently. But that's not clear, either.
