I think the real lesson of the Bush administration is that you can not leave any "left over" bureacrats.
ALL clintonistas should have been terminated immediatly.
Mineta of the transportation administration should never have been allowed to stay. He held up armed pilots.
And continues to do so. The program is way more involved, time consuming, and just a royal pain the a$$, than it needs to be.
For example, there is absolutely no reason why armed pilots need be reserve federal marshals, none, nada, zip, but that's what they must become if they wish to have the means to protect their aircraft and it's passengers.
