As the security people checking us all are so concerned about explosives, what protection is provided for them in the event that a suicide bomber masquerading as a member of staff decides to blow himself/herself up at the security check-point?
Surely the authorities must provide protective barriers (bombproof) at the least, to protect their staff and the innocent pilots/cabin crew/staff who are going through the checks at the time.
If the threat is serious, it does not stop at detection.
