I cant help but wonder whether White House Press Secretary Scott McClellan would be considered a "good apple" before his book or after ?

Scott McClellan's silence through his tenure which demonstrated loyalty to the group of which he was a member, did this make him a "good apple" ? Could it be that he went bad when he "told" on those outside the group ? Good Press Secretaries, Good cops, Good attorneys, Good anyone part of a collective do not tell...
