After the Thighbomber: Virtual Strip Searches at every airport?

The botched attempt to bomb a flight into the US by a the son of a wealthy Nigerian family, using explosive components strapped to his thigh, has led to an immediate techno-economic consequence, which is to speed up the process of installing terahertz wave or other body scanners in major airports, which if nothing else will provide a guaranteed income stream to Rapiscan and Qinetiq, who make these kinds of machines. Schipol in Amsterdam, where  announced they would be extending their body scanning operation and the British government almost immediately followed by saying that major British airports would be rolling out body scanning within weeks. Now, Canada is to do the same.

But, will this make a real difference or is it just more symbolic security? The scanners certainly ‘work’ in the sense that they do provide pretty good images of what is under the clothes of passengers (see below). However, interpreting what is seen is still no easy task and will the scanners will certainly not replace physical searches, but will add yet another extra layer of surveillant sorting and therefore delay. And there are questions over the effectiveness of the scanners in particular areas of the body. The Toronto Sun reports that trials at Kelowna Airport in British Columbia “left blind spots over the head and feet”, so these machines are certainly not the ‘silver bullet’.

Then of course, there are the privacy issues. I don’t have any particular problem with the technology, provided it is restricted to airports and doesn’t start to get used in other, more everyday, social settings (which given the rapid development of this technology is by no means certain). However, as I noted the last time I wrote about this, there will be many religious, gender-based and personal reasons for objecting to their use. The other question of course is whether, every time some lone lunatic tries something like this – that was, let us not forget, poorly planned and ineffective, and which should have been prevented by other conventional intelligence operations working properly – it makes sense to jump and harden security (or at least be seen to harden security) for everyone travelling internationally. Doing this just plays into the hands of terrorists as it disrupts the ordinary workings of an open society.

You would think after 4 years of trials at Heathrow, that British airports would now be able to work out whether or not they could and more importantly, should, use the various varieties of body scanners that are now available. However Manchester Airport is holding another trial starting from now at its Terminal 2. At least it will give a chance for the public to say what they think. The scans are remote – i.e.: the officer observing the images is not on the airport floor, which prevents the kind of scenario we mentioned in our Report on the Surveillance Society of lewd remarks directed at passengers. Personally, I am rather less concerned about this rather abstract view of my body being seen briefly as I pass through an airport than I am about my financial details and personal life being traded between private companies, or about being under constant video surveillance in ordinary public space in the city. However, the images, although ghostly, are detailed enough that genitals, deformities, medical implants and so on can be seen, and if this story is to be believed it would seem that there is no provision for women’s images to be seen by a women alone and men’s only by a man. This will make it entirely unacceptable to some people, in particular members of certain religious groups. But the scans are – at least, for now – voluntary, in that passengers can refuse and have a traditional pat-down search instead.

However, this technology won’t be staying in the airports for long. I reported back in July on stories that terahertz wave scanning could soon be made to fit into portable cameras. That raises a whole different set of social, political and ethical questions…
