When your passport is scanned at the border, it checks to see if you are on a terrorist list and if you have any wants/warrants out for you. It DOES NOT pull up your criminal history for DUI's etc. In order for a criminal history to be pulled there has to be probable cause that you are involved in criminal activity.
