Me either. DHS keeps waffling as well, they said no... then yes, then released a report that backed up NYC... now they say no threat again.
It would be nice to see them back up NYC, at least until the suspected threat window has closed. If not, there could be some middle ground. I can't blame the mayor for protecting his citizens though, it's nice to see after the Nagin debacle.
I've been wrestling with the same question. Maybe it's a disinformation plan with the hopes of catching the bad guy; at least I hope so.
The disconnect between DHS and NYC boils down to the old boys club that used to be the rift between the FBI-CIA. Each group wants to be right. Their's is the only intelligence that is good etc.
The difference here is that NYC has no choice but to err on the side of it's citizens safety. They did the right thing!
