I think "defence" could include guys and gals that have to use government computers on their tours of duty, Afghanistan, Iraq, etc......
That kind of works in our favour. It's hard to see how anyone with a computer in the battlefield can provide a reliable source for what is happening there. Even if they are editing from the base during their off time, I doubt that they have much there in the way of reference material. ;-)
They do however have digital cameras, and hence are being prevented from uploading useful images...
