"In an incredible online cock-up, the full details of a classified US military report into the shooting of Italian secret agent Nicola Calipari in Iraq have been made widely and publicly available. The error was caused by the US military itself, which posted an unclassified version of the report on the internet as a PDF file with large chunks blacked out. However, the Pentagon had failed to save the file with the edit lines in place so a simple copy-and-paste of the document into a word processing application revealed the report in full."
