I believe it was in the eighties that France and Britain tried to federalize this function, and it proved to be a disaster. Why? Perhaps a study about the failure is important, but not as important that it was failure.
I am very skeptical of any government project when someone such as Bill Clinton is elected into power. There can be federal guidelines, but there is not one scintilla of evidence that airport security is best handled by creating yet ANOTHER fed agency!
How anyone who is for a "Free Republic" can also be for more centralized government is beyond me.
