Planning a Terrorist Attack

Planning a clandestine attack using a weapon of mass destruction (WMD) is not simple. First, in order to promote an attack, the target needs to be viewed to have violated some ideology, policy, or other deeply held belief (“Terrorism, definition and history of,” 2002). Usually, a symbol of the offense will be chosen as either a specific target, such as the case of the World Trade Center, or as a vehicle or vector for the attack, as in the case of the U.S. Postal Service anthrax attacks (“Biological terrorism,” 2002; Marshall, 2002; “Weapons of mass destruction,” 2002). The dollar is an international symbol of capitalism and the might of the United States. In the current climate, especially with the declining U.S. economy, I would expect the money supply, itself, to be a viable vector for disseminating some sort of substance capable of causing terror. A dollar bill has a circulating life of 42 months and changes hands, on average, twice a day, and by impregnating paper money with a chosen substance, a single dollar bill could potentially harm more than 2,500 people during its circulation (U.S. Department of the Treasury, Bureau of Engraving, n.d.).

Almost as important as the vehicle is the impregnating substance. Chemical and radiological substances would be too easy to eventually detect, and the amount dispersed on each dollar bill might not be enough to cause harm. A live biological agent suspended in an aqueous nutrient solution could easily coat a dollar bill without detection and easily transfer to hands, surfaces, and other bills. According to Winfield and Groisman (2003), Salmonella enterica might prove to be a hardy pathogen capable of existing in such a solution for months. S. enterica is responsible for typhoid fever in humans. Escherichia coli, though a highly pathenogenic mycobacterium, does not have the same persistance outside of a living host. Both S. enterica and E. coli have detrimental health effects, especially for those with deficient immune systems.

Delivery and dispersion of the weapon would be the next consideration. This would have to be accomplished using a number of distribution points, geographically distant, that transfer small denomination bills easily both in and out, such as gasoline stations, convenience stores, fast food restaurants, and liquor stores. Using a website designed to track dollar bills (http://www.wheresgeorge.com), a single bill has been tracked in about two and a half years, as follows: Florida, Georgia, Florida, Indiana, Arizona, Oregon, New York, Tennessee, and South Carolina. Another has been documented as travelling from Ohio to Michigan via Kentucky, Tennessee, Florida, Texas, Louisiana, Texas, and Utah in a mere 212 days. This is evidence that general dispersion techniques will work well if initially geographically distributed.

Additionally, as the Salmonella bills are being dispersed, I would encourage a technological attack on various credit card networks. If the hacking results in increased network downtime, the American citizenry would be encouraged to use paper money more often, potentiating the transfer of the Salmonella bills. As a final coup de grace, when the American populace finally begin to realize that the money supply, itself, is tainted, I would encourage conventional attacks on banking institutions to include random bombings, shootings, and threats of the same. This would further drive the message against the U.S. money supply and could crash the economy.

This plan was developed in about twenty minutes. The terrorists of the day have had decades to consider such plans, and I for one am glad that they tend to be grandiose. When the terrorists realize the simplicity required of causing terror in the U.S., we need to be very wary.

Botulism: A Measurement of Occurrence

 Botulism, caused by the Clostridium botulinum bacterium, is typically caused by poorly prepared, home-canned foods and can cause symptoms as simple as blurred or double vision to full body paralysis, sometimes causing death (Centers for Disease Control and Prevention [CDC], 1996). The incidence of botulism is said to be extremely low with only 126 reported cases in the United States in 2003; with only eight attributable to foodborne vectors, the predominant cause is accidental contamination (CDC, 2004).

One of the concerns regarding botulism is its toxicity. Botulinum toxin is the most potent toxin known to man (CDC, 2006). This potency lends to botulinum’s ability to be used as an agent of bioterrorism, though most of the known cases have been shown to be accidental in nature (CDC, 1996; CDC, 2006). Another concern is the accidental or negligent contamination of any food prepared for wide distribution, such as canned vegetables from a large manufacturer.

Surveillance is important to identify each and every case in order to have the most accuracy possible when considering increasing or decreasing trends of incidence and prevalence of the disease. The cause of any increase or decrease in incidence of botulism should always be investigated.

Any increase of incidence could identify a possible problem while a decreased incidence could foretell efficacy in the efforts of mitigation. More appropriately, though, as Friis and Sellers (2009) show, further identification should be made in order to focus on specific descriptive factors, such as affected populations, the geography of these populations, known vectors, and factors of time. This process will ensure that more accurate trends are observed.

For instance, the CDC (2004) has stated that in a typical year, such as 2004, the incidence of botulism is less than 200. With incidence reporting covering the entire United States, increases or decreases in this crude number serve only to identify general changes in frequency; whereas, further identification of certain characteristics of the disease pattern will help to further isolate affected individuals and etiologies (Friis et al., 2009). Within the CDC’s (2004) data, infant occurrence of botulism is identified as the major contributor to incidence, thereby isolating the remaining occurrences to adults. The CDC has gone further to separate the incidences of botulism into three groups, infant occurrence, foodborne infection, and wound infection. A separate group is reserved for other occurrences relating to the use of pharmacological botulin.

Using descriptive factoring of the 2003 CDC data (2004), further geographic isolation of occurrences show that infant occurring botulism is fairly wide-spread with a small number of incidences in each of twenty-two States, though California and Pennsylvania account for about half of the reported infant occurrences. Foodborne and wound occurrences of botulism were isolated to Alaska, California, Colorado, Oregon, Utah, and Washington. Texas had the only two reportable cases classified as “Other”. Theoretical assumptions can now be used to show that the problem in Texas is resolved but should continue to be monitored, and food safety education projects should focus on home-canning in the western regions of the United States.

In conclusion, epidemiology is an important means of understanding and identifying causation and etiology, as well as preparing for mitigation and outbreak response. In this example of botulism, I have identified localization of the disease, common pathways of infection, or vectors, and means of helping to mitigate future occurrences of the disease. Botulism numbers are quite low, but dealing with other diseases of larger scale, grouping the data into useful subsets will assist in following the progression of the disease from outbreak to outbreak and in consideration of mitigation techniques employed.
