So, I repeat -- Few of the 9/11 hijackers made any attempt to disguise their names on flight and credit card records. A bunch had official Virginia IDs from the local DMV. All were flying on valid IDs that matched their valid boarding passes. So what is the ID check supposed to establish or prevent?
