The controversy over TSA airport groping and porno scanners

It looks like trouble is brewing over the so-called ‘porno scanners’, the new full-body scanning devices at airports that provide screeners with naked images of people. John Tyner, a resident of Oceanside, California near San Diego, refused to go through the machine or submit to the groping alternative. He was not only not allowed to get on the plane, he is now being investigated by the TSA because you are apparently not allowed to leave the airport if you refuse to be scanned, although he was initially escorted out. He could face a $10,000 fine. He has written about the encounter and posted the video on his blog and has now become something of a folk-hero.

November 24 has been declared National Opt Out day when travelers are being urged to refuse to undergo the full-body scans. Pilot associations are urging opposition, civil liberties groups are taking legal action, and petitions against them are being circulated. There are suspicions that the groping pat downs that are the alternative to those not wanting to submit to the full-body scanners are being used as a way to coerce people to use the porno scanners as the less humiliating option.

The promise that the images will be kept confidential have been shown to be false when the website Gizmodo released 100 images that they had been able to obtain. These images are of lower quality resolution than the new x-ray backscatter machines being used at airports. There are also concerns about the health effects of the radiation. A new site called Fly With Dignity has been started to collect horror stories about the TSA’s actions.

Ivan Eland describes another security measure that even I was not aware of.

Another bizarre security addition that I have recently experienced is the plastic cage. Last week I was flying and was randomly selected for the dreaded “secondary screening” (it sounds ancillary but is just annoying). The security woman put me in the cage (fortunately it had air holes), locked it, and told me that I wasn’t getting out until she swabbed my hands (presumably for potential chemical residues from bomb making).

Art Carden at Forbes calls for the abolition of the TSA. Carden also makes a point that has been known for a long time but which only now is being widely voiced, that the threat from dying in an airplane terrorist attack is far less than the threat of dying on the drive to and from the airport, so why are we so freaked out about airport security? Journalist Jeffrey Goldberg, in this interview with Stephen Colbert, gets really worked up over the porno scanners.

The American people have for a long time ignored blatant abuses by their government of the constitution and basic human and civil rights. They have condoned wars started on false pretences, torture, denial of habeas corpus, indefinite detention without trial or access to lawyers and family, kangaroo courts rigged to produce guilty verdicts, killing of civilians in other countries by predatory drones, murder of American citizens merely on the president’s say so, and so on. Truly horrendous crimes have been greeted with a shrug that ‘they’ probably deserve it and that these actions make us safer.

Could it be that intrusive airport security, of all things, is the issue that awakens people from their stupor and make them finally realize that the national security state is out of control, and that this groping and porno scanning is merely a symptom of a government drunk with coercive power that thinks they can do anything to anyone with impunity? Will people from all over the political spectrum seize this opportunity to join with others and pull on this thread and begin the unraveling of the national security state? Or is it that they are upset because in this case the professional classes are being directly imposed upon and they will become meek and docile again if this particular intrusion is removed and the government goes back to abusing the powerless?

This protest may also fizzle out with the usual sniping based on party labels. Republicans seemed to be just fine with the Bush-Cheney regime violating their rights but now that Obama is in the White House they are starting to grumble. Will the Democrats who protested loudly against Bush-Cheney now meekly support the Obama regime on this issue?

I hold out a slim hope that this is the beginning of a new valuing of personal liberty and privacy and the rule of law.

On free will-8: The 1983 and later experiments of Benjamin Libet

(For previous posts in this series, see here.)

In 1983, Benjamin Libet and his associates did some experiments that were similar to the 1963 Grey Walter experiment but with the added feature that the patients could observe the equivalent of a clock and thus note when they made the decision to act. This enabled a more objective determination of the time when they first had the conscious thought to carry out the action and not depend upon a possibly misleading feeling of surprise to infer the ordering of events.

One of the key original papers was published in the journal Brain (Time of conscious intention to act in relation to onset of cerebral activity (readiness-potential): The unconscious initiation of a freely voluntary act, vol.106, p. 623-642, 1983) which does not seem to be available online but you can read online a later review published by Libet in 1999 (Do we have free will?, Journal of Consciousness Studies, vol. 6, No. 8–9, 1999, pp. 47–57) where he summarizes his findings and its implications for free will.

The Despicable John McCain

His disgusting weasel-worded campaign against giving gays their rights deservedly gets hammered on The Daily Show. The last bit It Gets Worse, based on Dan Savage’s It Gets Better campaign, is a thing of beauty because it is absolutely true. People who are on the wrong side of the fight for equal rights for marginalized groups always, always end up being despised.

On free will-7: How reliable a historian is the brain?

(For previous posts in this series, see here.)

In post #6 in this series, I discussed the 1963 Grey Walter experiment in which patients who had electrodes implanted in their brain’s motor cortex that could send a signal to advance a slide were surprised that the projector seemed to anticipate their decision to advance the slide. Does this mean that their unconscious neural activity had decided to advance the slide before telling the conscious brain that it had decided to do so? If so, it seriously undermines the idea of free will. In his book Consciousness Explained (1991, p. 167) which discusses the experiment, Daniel Dennett warns that it is premature to accept this conclusion because it is based on the articulated sense of surprise reported by the patients, and the brain is not the most reliable of historians.

On free will-6: The 1963 Grey Walter experiment

(For previous posts in this series, see here.)

In the previous post, I provided a schematic description of two models of how the brain works, one with free will and the other without it. The traditional brain model with free will is given by

(D)                                    GES
                                        ↓
will → conscious thoughts → unconscious neural activity → action

Our genes (G), environment (E), and the inherent randomness in the laws of nature (S) all contribute right up to the present instant to the brain’s structure and unconscious neural activity. But in this model, there is a separate branch in which our (uncaused) free will makes decisions first which manifests itself as a conscious thought. In this model there should be a definite temporal sequence in which the act of will occurs first, followed by conscious thoughts, then unconscious brain activity caused by that conscious thought, and finally the action.

On free will-5: Models of how the brain works

(For previous posts in this series, see here.)

It is time to look at specific models of how the brain works.

In the previous post, I pointed to a paper by biologist Anthony Cashmore which argues that our brains are the product of genes (G), environment (E), and stochastic (i.e., random) processes (S). This GES combination influences the unconscious neural activity in our brains, which in turn gives instructions to the motor neurons that control our actions. So the causal and completely physiological chain goes like (A):

(A) GES → unconscious neural activity → action

The directions of the arrows signify the causal relationships. Our bodies are in a state of constant activity, with hearts beating, blood flowing, digesting food, breathing, secreting chemicals, producing new cells and disposing of old one, and so on, all of which take place without us being aware of it. I think everyone (except those religious people who can’t bear to see god not taking part in every single activity) will accept that our brains control and moderate all this unconscious behavior. What is in dispute is what gets added on to this basic model.

On free will-4: The implications of modern physics for determinism

(For previous posts in this series, see here.)

The possibility of the existence of Lucretian random swerves that destroy determinism received a boost in the early twentieth century with the advent of quantum mechanics and its associated uncertainty principle that eliminated strict classical determinism.

Believers in free will seized on the inherent randomness built into these newly discovered laws of nature to argue that free will could exist and manifest itself at the quantum level. However, as our understanding of quantum mechanics has increased, few scientists seriously accept this possibility anymore because of the many problems such a model has. After all, random processes are, well, random, meaning that they are not subject to being controlled. If indeterminancy at the quantum level is what undermines determinism, what we would have is not free will but what we might call ‘random will’, in the sense that we would be acting according to the random outcomes of quantum level phenomena over which we have no control. Furthermore, while individual quantum events may be completely indeterminate, they do obey laws that enable us to accurately predict statistical outcomes, so these events cannot be truly free. Free will as popularly conceived does not consist of random or statistically predictable behavior but of the ability to deliberate and determine specific outcomes. No mechanism has been proposed to suggest how that might occur.
