Dangerous Airport Security Fail

While leaving the Santorini (Thira) National Airport in Greece on October 6th steven j hubbard found that was able to pass through the security check point without being stopped, even when wearing a bag and having the metal-detector go off. Two fellow travelers thought this was hilarious and passed through security (one also with baggage), also without being stopped. While hilarious the implications are definitely terrifying, what do you think?
