Alas, I have more sad news of documents disappearing. The first incident could easily have been avoided. According to the Globe and Mail, it seems that technicians inadvertantly erased e-versions of documents from the Air-India trial that were about to be released. Their deadline has been pushed back from April to September on account of the incident.
The second incident comes to us from the States. The New York Times reports (may need a subscription) that a U.S. site housing an archive of Iraqi documents was removed when sensative material was found on it. The site is under review.
