Terror threat

So this new Bin Laden tape makes explicit threats of an impending attack on the United States.

But the Homeland Security threat meter hasn't moved a bit. Still yellow.

Interesting. I don't think we've seen a terror warning since the election.

So...

Either Bin Laden's tape doesn't actually mean there's any new threat, and all the crap on TV about it is propaganda, or the Homeland Security thingy is merely propaganda.

I just want to know which crap is the crappiest.

Of course, there's exactly one other logical possibility: both.
