Should the FAA have been ready for 9-11?

According to this story from the New York Times via Fromthewilderness.com, the FAA actually had more warnings about terrorists possibly hijacking a plane and using it as a bomb than we previously thought. Apparently the FAA had numerous warnings, including some that mentioned Bin Laden and Al Qaeda by name, but did not act on them. That is kind of scary, if we had that warning and then did nothing. That does not necessarily mean that we absolutely could have prevented that from happening, but you never know. Personally though, I believe that had the FAA rolled out the security precautions then that we know have, there would have been mammoth opposition from the public, arguing that they were being made to wait unnecessarily. Before you argue that point, you have to realize that the FAA would not have been able to disucss the exact threat with the public before it happened. Some things should have been changed along time ago, like prohibiting box cutters and anything else sharp, on airplanes.
