I'm so sorry for your loss.
Look at what happened in Boston yesterday: a whole town stopped in its tracks because some advertising agency decides it would be a good idea to put electronic devices on bridges and tunnels.
NYers recently had to endure a natural gas "scare" and before that had to put up with a small plane gliding around the canyons of NYC before smashing through a high rise. In each case, cops were called out in the droves. Should all of these things been ignored because they turned out to be non-terrorist acts? I don't think so.
Thaks, miss marmelstein, for caring.
