"Bullshit" is right!
What would it matter if the Chinese get the source to anti-hacker code used by the US? The good stuff is from Russia! And the Linux security code (SELinux) is open source and funded by the NSA.
But the real problem with the American gov't machines is that their sysadmins don't implement any security at all. How else can they be used in botnets and be perused for alien technology? The locks and burglar alarms are only good when they are deployed, not stuffed in the closet.
