"There are documented incidents of P2P file sharing where Department of Defense sensitive documents have been found on non-U.S. computers with no protection against hostile intelligence," the Patent and Trademark Office explained in a statement.
yes, except they weren't obtained via p2p networks, as they well know...
huge numbers of the US governments "sensitive material" is stored on windows computers, which are not under the control of any US government employee, they are under the control of IRC script kiddies that have got hold of the latest script kiddie bot and uploaded it to the wide open systems
they are more than aware of this - they even had the nerve to arrest someone for using their systems to store his files on, and completely ignored the fact that it was wide open in the first place and that's why the files were on it, they also ignored all the trojans on the various systems being used (reported to them by the person who they arrested)
what is surprising is that all of this is not only known to them, but also publicly known as well, so how they can dare to claim that it being possible for a p2p client to be re-configured to share sensitive files by a government employee is a security risk when they already have systems with full public access...
