How about this:
There are lots of "weird" things going on the last couple days.
The "New" Congress just convened.
Perhaps Osama et al are just acting on their knowledge that weakness now reigns?
It makes more sense than adjourning for a football game. There are too many weird things happening all over the country, too many false alarms. Maybe it's all just designed to make everyone jittery, but maybe there is something bigger planned. Maybe that missing Indonesian jet isn't at the bottom of the sea.
