Conrad Burns Issues Dramatic Taxi Cab Terror Warning (w/poll)

Republican Senator Conrad Burns, a close ally of President Bush, said yesterday at a campaign event with Bush, that the U.S. is threatened by  a "faceless enemy" of terrorists who "drive taxi cabs in the daytime and kill at night."

Please stay clear of taxi cabs for your own safety! And, urge the White House to engage tactical strikes against all taxis now!
How has the government allowed these taxis to roam our streets if Burns, and presumably other officials he works and spends time with, have known that terrorists are killing at night after their taxi shifts?  Talk about weak on security...
