The former head of El-Al security said on TV yesterday that he personally performed tests that showed the Skycap system was completely insecure.

He placed 'dummy' bombs in bags then gave them to the Skycap with a large tip. All the bags made it to their destinations even though he never got on the plane. I'm not sure whether he even had a ticket, but I'm sure with a big enough tip and a lie about misplacing your ticket this wouldn't be a problem, either.

If you want a secure system, you cannot in any way rely on people who accept tips and/or who are paid minimum wage.

Tips are, essentially, bribes for delivering good service, and you cannot expect the people expecting them to distinguish with perfect accuracy the difference between helping a harried businessman and aiding a well-dressed criminal.
