Uh, the 2000 Census revealed that over 50% of those living in Florida weren't born in the U.S. -- and that's not counting illegals. It's no coincidence that the hijackers felt safely anonymous here (just another group of foreigners), or that South Florida votes overwhelmingly Demoncrat.
OK, this guy was on a fligth from Miami. The Shoe bomber (now isn't that an interesting name for him) was on a flight to Florida. We had a bunch of the 9-11 highjacker/terrorists who trained and stayed in Florida. Let's not even talk about the "voting chad of broward, or the butterfly ballot fake controversy." But let's just look at the terrorist aspects, including the anthrax letter to the tabloids and the kid who flew himself into a bank building. The terrorists and their sympathizers like living, going to or coming from Florida.
What are some odd pieces of informaiton about Florida that might explain this. You have suggested that Florida is a melting pot of non-US born folks within the US, with a lot of illegals. I suspect that you probably are implying that people in the state (including the police) have a don't ask-don't tell attitude toward people who may not legally be in the Country and this attitude is an important cover for terrorists and their sympathizers.
