This sounds more like someone seeking attention. Terrorists don't announce that they have a bomb or suspicious package to police.
Moveon DUmmies maybe.
Big silly hat alert!
Someone else in the car said "I hope you don't search my car like they did in Mexico"
I'd guess its 50/50 that a Tancredo fan Freeper's car is about to be blasted by a water cannon...
Unless they want to MISdirect police, bombsquad into looking at their DECOY diversion.
