Sounds like a phoney threat but then again, postmarked in Phila. and originating from Cherry Hill New Jersey ... it might be real. The lovely state of NJ harbors many terrorists. Some areas are havens for this scum of the earth.
Philadelphia postmark may be just another stop along the I-95 corridor.
"The lovely state of NJ harbors many terrorists."
We surely do. I've said it over and over and I'll say it again now, they should have gone DOOR TO DOOR in this state starting on 9/12/01 but they didn't. NJ is the most densly populated state in the nation and it is filled with immigrants, esp. Middle Easterners and Asians, along with everybody else.
Take a look in any Democrat-controlled U.S. city that has repudiated the Patriot Act; that's where you'll find the Islamofascist vermin, feeling right at home with their fifth column Rat allies.
