Scott McClellan, Colin Powell, etc. It's so safe for them to talk about how they were opposed to administration policies or at least upset at them after they've left the White House. Of course they're in it for their own skin. Public servants are supposed to serve the public and not their own butts. If you think administration policy is going to hurt America, resign and talk. Don't wait until you get a book deal to do it.
Where they stand morally is the guy who sees a drunk walking to his car, gunning his engine, then saying the next day "I thought it wasnt a good idea, and now that bus full of kids is dead."
