I am glad the dragnet stopped a lot of people. But the FBI and DOJ warnings persist because they are not confident they have found everyone (people still here associated with the 9/11 groups)) that can launch further attacks using explosives, chemicals, biologicals (small pox is still on the radar screen) and nuclear devices. It is not just me or Jim Patterson who is warning the public about this, it is Aschcroft, the DOJ, Mueller and the FBI.
The others who were here before 9/11 and are still here are 5 AlQaeda cells ( identified by Wash Post piece by Bob Woodward), three Abu Nidal cells and countless Hamas cells (OKC also) in the US that the FBI has deliberately still not moved against for political reasons. These groups can pick and chose when they may strike next. Do not take comfort yet from the relative quite and calm we have currently. Our own government is warning us there is more to come.
And there is the specter of more immigrants coming into the US that were not here on 9/11 but are here now or who will be here soon. There were several articles on FR about Syrian and Saudi pilots being allowed to go to Dallas flight schools under questionable circumstances well after 9/11. The borders with Mexico and Canada are not secure enough yet and even Aschroft has said that.
