Would RedHat come out in the open and announce that selinux is a backdoor for the 
NSA? No, that would eliminate their OS. Everyone would dump them, Fedora also, in 
droves!

Honestly, I said it originally with tongue firmly in cheek, but I do have my suspicions. 
The NSA has some of the best computer security guys outside of Google, who is to 
say they could not write some excellent code that takes others a long time to figure 
out what it is really doing? lol
