Coming clean and telling what this really was (anti-Israel/Jewish terrorism on US soil) would be a CONTRADICTION to their massive TV propaganda program of "I Am An....American!" and Bush's visits to mosques.
One can see that political correctness has so fully crept into the new Administration's FBI just as it teemed there under Clinton. It is so obvious what is going on it isn't even funny. The TRUTH of the July 4th LAX Terrorist Incident is being sacrificed on the altar of kumbayaist political correctness.
But what they did not bargain for is a hard core and growing core of sophisticated observers (as evidence on this FR page) who are not gullible and who help spread potent counter arguments to show them off for what they truly are, embarrass them, and thwart their plans to paper these and other incidents over for the sake of their narrow agendae.
