Personally, I'm rather grateful to the news media for finding and reporting on the flaws of our security system! I just feel sorry for the airport security people who, often through no fault of their own, are made to look stupid!
Every time they find a flaw, airport security take steps to plug the hole and our airports become that little bit safer!
However, the really weak links in the chain are on-line check-in and self-service kiosks until bio-metric passports and iris scanning technology is introduced! Of course, the other massive weak-spot is the obsession with staff-cutting that is a current epidemic within the aviation industry as a whole!
