I do not understand the logic behind reverse screening. Seems to me that the logical thing to do is to escort all arriving passengers out of the terminal directly. That way, those who have arrived at their final destination are free to leave; those who have a connecting flight will need to process through the security checkpoint. Even so, seems to me that it's closing the barn door after the horse has left.
