Weehawken is home to the worst money management firm I ever had to deal with, and to the worst tech-support guy ever to blight the planet (who worked for said MM firm). If Weehawken were to vanish overnight into a giant sinkhole, I would not be at all surprised. I can't be the only person that guy has pissed off.
Some years ago a disgruntled customer shot up a GMAC office near me. I don't think individual acts qualify as terrorism, unless they're organized crime.
