A Simple Request

Josh Marshall wants to know why he can't know where his money is going:

I can see as well as you that my calls for disclosing the identities of the AIG counter parties have fallen on deaf ears. When Sen. Cantwell (D-WA) asked Secretary Geithner today who they were, his answer was an argument that letting AIG default on its obligations posed too grave a systemic risk to the US and global economies -- a claim which I concede may be true but nevertheless ignored the question: who's getting the money?

So how about this? Can we get a clear explanation of why we can't know?
