Don't think this is anything about enforcing rules, or actually achieving a measured improvement in security. It's all about power management and self promotion.
If the Department of Infrastructure and Regional Development can beat their collective chests by making an example of a few unfortunates then that, in their pea brains, will be worth the effort and taxpayer expense.
I can see the Herald Sun headline now. "QANTAS CAPTAIN DETAINED AND CHARGED FOR NOT DISPLAYING CORRECT IDENTIFICATION. FLIGHT DELAYED. QANTAS SECURITY INVESTIGATES"
Remember the overriding reason for the existence of airport security.
1. Provide the illusion of security as we all no real security is all too hard.
2. Over inflate the importance of airport security in the media at every opportunity in order to reinforce our power base.
3. Using points 2 and 3 justify spending millions of taxpayer dollars on equipment which is of absolutely no benefit whatsoever (walk through full body scanners) but by spending all this money further justify our yearly budget.
4. By completing points 1 to 3 above, justify the employment of several thousand parasites that would otherwise be unemployable.
So, yes. I'm not surprised at all that these inspections are in the way. They will catch those whose ASIC has unfortunately blown upside down in the wind. They will make an example of those individuals. Puff out their chests and say what a great job they're doing.
