I believe People working on the inside hand em off.
The latest wikileaks stuff--the international diplomacy stuff--was *allegedly* done by a pentagon worker. He bragged about how easy it was, he would bring a blank cd labeled lady gaga CD to work (his example) and then when he got there he'd format it and split it, burn encrypted compressed copies of all the memos he could get his hands on and put some lady gaga on there too in case anyone wanted to listen to it.
The pentagon is now going to make all their machines unable to write data on any sort of drive, which sounds impossible to me, but maybe one of you tech people, Emma? Shea? can explain it.
