Just my Washington two cents...

I don't buy the NSA having a secret access technique to Windows for the following reason:

1. If they did, and it got out, MicroSuck would loose all of its overseas market, something even they are not stupid enough to do...

2. The NSA has enough power to break into computers with out a back door, so why risk the exposure...

3. If the NSA did it we would never know....

So those are my non-technical reasons why I don't buy it!
