If you haven't already read this week's U.S. News cover story on the CIA by my colleagues Linda Robinson and Kevin Whitelaw, you should do so. It's a first-rate piece of journalism, reporting the facts without disclosing things that should be kept secret and presenting the very different interpretations of what's going on at the CIA. Is CIA Director Porter Goss purging too many career veterans? Or is he cleaning out deadwood and reinvigorating a worn-out agency? Robinson and Whitelaw report; you can decideor keep your mind open to the various possibilities.
