Computers at the Oil for Food inquiry

This week I attended a hearing of the Oil for Food inquiry. This is looking into if payments by Australian companies to the Iraqi Regime breached any laws. The inquiry room is hitech, with several dozen LCD computer screens and projector displays for electronic evidence. Much of the evidence is "born digital", being copies of email messages. But the absence of most of the header fields on messages worries me. More at http://www.tomw.net.au/technology/it/courtech.shtml.
