Full Body Scanners: Security Theatre at its Finest.

In my travels through the USA I became intimately acquainted with their high level of airport security. Upon entering the country we were finger printed, photographed and grilled about what our trip was about. There was also the long lines for getting through the metal detectors and full body scanners, usually taking up a good 45 minutes of my time to get through. I was never chosen to go through the backscatter x-ray machines (nor did I see any of the newer millimetre wave ones) but I did see many people go through it. Most of them weren’t exactly what you’d call a security risk (mostly people in wheelchairs) but I knew exactly why those machines were there: to make everyone feel safer without actually being so.

This is what is referred to as security theatre. These scanners are supposedly better at detecting things that slip by metal detectors which they accomplish by using low-energy x-rays that penetrate through clothing. Solid objects then should become obvious and should something suspicious be identified the passenger can be taken aside for further searching. Trouble is the machines aren’t terribly effective at what they’re designed to do and the back-scatter x-ray type machines emit ionizing radiation (not a lot mind you, but there’s been minimal research done into them). Using them then seems like a pointless exercise and indeed even though they’ve been in operation in the USA for quite some time the jury is still out on whether they’re actually being effective or not.

So you can then imagine my surprise when I find out that we’ll be getting these scanners at all international airports in Australia:

PASSENGERS at airports across Australia will be forced to undergo full-body scans or be banned from flying under new laws to be introduced into Federal Parliament this week.

In a radical $28 million security overhaul, the scanners will be installed at all international airports from July and follows trials at Sydney and Melbourne in August and September last year.

The Government is touting the technology as the most advanced available, with the equipment able to detect metallic and non-metallic items beneath clothing.

Now we won’t be getting the dubious back-scatter style ones here instead we’ll have the newer millimetre wave ones that don’t emit ionizing radiation. That’s the only good news though as they’ve also amended the legislation that allows you to turn down things like this in favour of a pat down, with the penalty for refusing to go through one being that you’ll be barred from your flight. To top it all off the transport minister Anthony Albanese sealed it with this choice quote “I think the public understands that we live in a world where there are threats to our security and experience shows they want the peace of mind that comes with knowing government is doing all it can”.

It’s almost like he knows these things are a useless piece of security theatre, but is going ahead with them anyway.

More than a decade has past since the events of 11/9/2001 and we’ve yet to see a repeat, or an attempted repeat, of the events that led up to that tragedy here or overseas. The health and privacy concerns aside the reality is that these scanners don’t really accomplish what they’re designed to do and are thus just another inconvenience and waste of tax payer dollars. I can understand that there are some who will feel safer by seeing them there but that doesn’t change the facts that they’re just another piece of security theatre, and a costly one at that.
