I would imagine the Zarqawi information has something to do with the notice. Today's release to the public about the Grand Central Station plans found after the Madrid bombing might also have them taking extra precautions, especially with the anniversary of that attack coming up next week.
Yep, well the news updates seem to reflect the opinion that maybe/maybe not it was Grand Central Station.
My PERSONAL OPINION is that NY seems to continue to be a potential target. I could be wrong and I hope I'm wrong. Being prepared is a good thing, no matter where one lives; no matter what alert level we are on.
