The forgot one paragraph:
The disclosure came only after poisonously partisan Democratics and this paper charged the administration with false alarms and election year "fear-mongering", thereby blunting the effect of the White House's initial warnings. Only after this disclosure did these nattering nabobs concede that additional security "might be a good idea".
Bingo. It appears the scorching of the Administration by the leftists over heightened terror alerts led someone to back up the warnings with specifics.
Not that this excuses leaks, but it explains them.
LEAKED Right after KERRY GOT His Intelligence Briefing, HMMMM, and to The OLDE Gray Lady, his Campaign Paper of record, Hmmmmmm.
