Security is immunity from the will of others.

Power, oversight, and photography

As this disturbing alleged situation demonstrates, you may be ordered at some point to delete photographic or videographic evidence of an event without appropriate justification.

While there may be situations in which security concerns are justifiably paramount, there are also many situations in which those who have authority simply wish to avoid facing any accountability for their actions. Given the conflict of interest involved for those law enforcement officers on the scene, it seems prudent to retain any photographic or videographic evidence you have produced, even if you are asked by them to delete it.

After all, any impartial evidence that exists can only help in any subsequent official proceedings. The absence of such evidence is likely to strengthen the bias of impartial adjudicators towards those with authority, as opposed to those who simply happened to be witnesses.

Ranking energy technologies, from wind turbines to corn ethanol

Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford, headed up a study to quantitatively evaluate different electricity generation options, taking into consideration their impacts on climate, health, energy security, water supply, land use, wildlife, and more:

The raw energy sources that Jacobson found to be the most promising are, in order, wind, concentrated solar (the use of mirrors to heat a fluid), geothermal, tidal, solar photovoltaics (rooftop solar panels), wave and hydroelectric. He recommends against nuclear, coal with carbon capture and sequestration, corn ethanol and cellulosic ethanol, which is made of prairie grass. In fact, he found cellulosic ethanol was worse than corn ethanol because it results in more air pollution, requires more land to produce and causes more damage to wildlife.

It is naturally very difficult to assess the validity of any particular research methodology, given uncertainties about matters like the future development of technologies, the evolution of the global economy, the availability of fossil fuels, and so on. Nonetheless, it is good to see serious work being done on comparing the overall appropriateness of different energy technologies. Given the unwillingness of many states to impose serious carbon pricing solutions, and the tendency of governments to ‘pick winners’ when it comes to technologies being subsidized, the more high quality data available, the better.

While I haven’t looked over the study in detail, it does seem like the strongest objections raised against nuclear (which is ranked very badly) aren’t really about the environment or economics. The risk Jacobson highlights most is that of nuclear proliferation, and the dangers associated with making fissile material more widely available. Proponents of a nuclear renaissance probably won’t be keen to see discussion of “the emissions from the burning of cities resulting from nuclear weapons explosions potentially resulting from nuclear energy expansion.”

The entire study was published in Energy & Environmental Science, and can be accessed online.

A global response to the threat of asteroids

Climate change is not the only threat to humanity that the United Nations has been called upon to deal with. Another risk that bears consideration is that of the inevitable collisions that will occur between our planet and other big rocks in space. A group called The Association of Space Explorers has raised the issue recently, arguing that the near pass of Asteroid 99942 Apophis in 2036 should prompt some coordinated global thinking on appropriate responses to possible impacts. Their report refers the the Tunguska event of 1908, a three to five megatonne explosion which started fires large enough to engulf New York City. Apophis has a 1-in-45,000 chance of striking the Earth, but would generate a 500 megatonne blast if it did so. On an astronomical timeline, it is inevitable that an object of this magnitude will eventually strike the Earth.

The group has released a fifty page report entitled Asteroid Threats: A Call for Global Response (PDF). It covers both some technological options for deflecting incoming asteroids and decision-making processes through which such plans could be put into action. It makes a strong case that the probability of successful deflection is much higher if action is taken early. An extension of that is the need to take decisions before it is certain a collision will occur: a situation that significantly increases the probability that such a decision will need to be made within the foreseeable future.

Metal detectors and carry-on restrictions for Greyhound travel

The policy of restrictive carry-on rules appears to be spreading from planes to Greyhound buses. Apparently, as of December 15th, passengers boarding them in Ottawa will be forced to put everything aside from “medication, baby formula and small handbags” in checked baggage. No matter that those rattling baggage holds are hostile territory for cameras, computers, and other delicate items. Likewise, no matter that the logic of security on intercity buses differs substantially from the logic for aircraft, as I have written about previously. The system has already been introduced in Edmonton, Calgary and Winnipeg.

To summarize my earlier post:

  • With a plane under their control, hijackers can fly to distant states that might assist them. The only way to stop them is to shoot down the plane, killing everyone on board. Buses are comparatively easy to stop.
  • [S]omeone in control of an ordinary plane can kill a lot of people. They can certainly kill everyone on board. They can also kill many people on the ground. Similar risks do not exist in relation to buses.
  • [I]t isn’t clear that this strategy won’t simply displace any violence that was to occur to a different venue. If I want to harm a particular person, I can do so in a place other than a Greyhound bus. The same is true if I just want to hurt people at random.
  • If you are really determined to hurt people on a bus, you can get on at a rural stop, rather than a bus station with metal detectors

It seems that the best low-cost and relatively low-carbon form of intercity travel is about to be needlessly constrained. It remains to be seen whether Greyhound proves enduringly committed to the new procedures once customers start appreciating just how inconvenient and unnecessary they are.

Disorder and bad behaviour

Research conducted by Kees Keizer of the University of Groningen has demonstrated that the willingness of people to litter and steal increases when they are in disorderly surroundings. When experimental subjects were exposed to law- or rule-breaking, they were significantly more willing to litter, trespass, and steal. This is suggestive of how even relatively subtle cues in our surroundings and the behaviour of other people can affect our behaviour, perhaps in ways we aren’t consciously aware of.

One could certainly theorize about the social and evolutionary roles of such behaviour. When an individual is in an orderly situation, the costs associated with rule-breaking may be higher. It is clearer that they are making an individual contribution to the problem, and the absence of other violations suggests that enforcement exists and is effective. Conversely, those surrounded by disorder often have more of a need to fend for themselves, as well as less of a risk of being singled out and punished.

It would be quite interesting to see this kind of research extended, and some of its conclusions used to create new policies. The kind of harmful anti-social activities that could theoretically be combated seem very numerous: from the corruption of government officials to insider theft in the workplace to the dumping of toxic materials in parks or bodies of water. While this study provides no direct evidence that modifying the environments in which people find themselves can alter their behaviour, it does seem plausible and worth looking into.

Drug tests and false penises

In another drug war skirmish, the owners of a company selling fake penises and urine for beating drug tests have pleaded guilty to charges of conspiracy in an American federal court. The situation demonstrates how any security situation generates countermeasures. Banning outside alcohol from football games led to the Beerbelly, just as submarine warfare led to aerial sub-hunting patrols and new convoy techniques. Of course, some threats and responses are higher-risk than others.

Surely, none are worthy of concerted government attention than ferreting out the recreational marijuana users (as opposed to the users of legal alcohol) from within the workforce.

Oil tanker captured off Somalia

Yesterday, Somali pirates seized a Saudi Arabian oil supertanker, carrying about two million barrels of oil. It is a tangible demonstration of just how insecure marine traffic in some parts of the world has become. According to the Associated Press, “piracy is considered the most lucrative work in Somalia.” It is estimated that pirates have taken in $30 million in ransoms this year.

As discussed here before, piracy is a growing challenge for private shipping firms and the world’s navies. In the end, maritime insecurity derives from the lack of security on land. Pirates need means to acquire arms and recruits, as well as means to collect and launder ransoms and sell stolen goods. In the end, it is just another reason for which failed and failing states are of global concern.

New developments in spam

Remarkably, it seems that 70% of the world’s spam emails were originating from an American firm called McColo. On November 11th, two American internet service providers cut them off from the web, leading to the huge drop in the global volume of spam. It is estimated that 90% of spam messages are actually sent by computers that have been compromised by viruses, which makes it a bit surprising that such a drop could be generated by disconnecting one firm. Clearly, it is a network that needed central direction to operate. Those that emerge as successors will probably be more robust, located in more unpoliced jurisdictions, or both.

While the respite is likely to be temporary, the situation may reveal some useful information on the practice and economics of spam. This unrelated paper (PDF) examines the latter. The researchers infiltrated a segment of the Storm Botnet and monitored its activity and performance. On the basis of what they observed and estimates of the rest, they concluded that the botnet earned about 3.5 million dollars a year by selling pharmaceuticals. While that isn’t an inconsiderable sum, I suspect it is less than is being spent by companies combatting the flood of spam messages themselves.

Celebrating soldiers, celebrating peace

The problematic nature of Remembrance Day has been covered twice here already, in 2006 and 2007. My question for today is this: would it be better to have two separate holidays, one of which is unambiguously pacifist and committed to recognizing the horrible character of war, and another in which the sacrifices of veterans are marked?

The first occasion would mostly be about civilians, since theirs is the primary experience of contemporary war. The second would still need to address difficult questions about why sacrifices on one side were more noble than those on the other, as well as what kind of conduct we should consider acceptable or laudable in war.

Spying on North American weather

Most weather systems in the Atlantic move from west to east. As a result, the Allies had a tactical advantage during the Second World War. Their weather stations in North America provided information that was useful for making plans in the Atlantic and European theatres of war.

The Germans made a creative effort to alter that balance by secretly planting a weather station in Labrador. The automated station was transported by U-boat and installed under cover of fog. Unfortunately for the Germans, the station only operated for a few days and the U-boat sent to repair it got sunk.

You can see the weather station on display at the Canadian War Museum, which is free on Thursday evenings.
