I don't know the definition of minor offence, but 50 million sets of criminal fingerprints are in the criminal history of the FBI; 50 million Americans have a criminal history, and it's not jaywalking. These are criteria felonies. Therefore when a felony offence is pulled up on the FBI's criminal history and transmitted to TSA, then they mitigate that risk. And they do not share with us or anyone else that we know of exactly everything they do. In some cases they go to the extent of interviewing friends and relatives of the transport worker to see what kind of person they are. So they go very deep besides just the criminal history background.
