10 Terrorism & Recruitment (spread of illness models) One of the dangers of terrorism is recruitment of terrorists abroad Currently Pakistan Remember 9-11, & how many skyjackers were Saudis! Remember Al Qaeda in Iraq and the Sunni-Shia clashes Another current worry is domestic recruitment, US citizens becoming terrorists They have passports; may be hard to detect 10
11 Points About Terrorism Definition: The killing and injuring of innocent civilians for political purposes The perceived threat from foreign terrorists to the USA (at home) is relatively new (since 9/11) Earlier skyjackings in the US were not by terrorists Terrorism has been a threat since World War II in Europe, much of it connected to the Middle East We can learn from comparing the US reaction to skyjacking, and attempts to control it
12 http://www.encyclopedia.com/to pic/terrorism.aspx TERRORISM Although the terrors of war and criminal violence have been known since the dawn of human existence, the concept of terrorism as a form of political violence originated in le terreurof the French Revolution. Initially a word for the brutal excesses of a revolutionary government (some forty thousand persons were guillotined), by the late nineteenth century "terrorism" referred almost exclusively to the antigovernment violence of groups such as the Russian Narodnaya Volya ("Will of the People"). Since then, the designation of particular groups and actions as terrorist has varied with political assumptions and aims.French Revolution To defenders of government, almost any violence by opponents may be defined as terrorism. To opponents, virtually any governmental effort to restrain or repress opposition may be defined as terrorism.

24 Learning from History Skyjacking in the USA first in the USA was 1961 in contrast to skyjackings abroad, at most one skyjacking at home was, maybe, politically motivated by a someone with connections to the Balkans

30 US Skyjackings Motivated by self-interest (greed/economic person) Rapid increase from nothing, kind of like “the spread of disease models” Know of all instances; no figure of unreported crime i.e. skyjackings Eliminate the expected benefit to the prospective skyjacker by increasing the expected cost US Marshalls on vulnerable flights (30,000 commercial flights/day) Airport inspection
43 Borch Model of Inspection Two actors employee(embezzler) & firm skyjacker & airport security Two sets of values or payoffs to the outcomes No dominant strategy for either actor Need to keep your adversary guessing Embezzler’s expected outcome: break even Firm’s expected outcome: dead-weight cost of inspection

61 Conclusions The expected value to the crook (embezzler) is zero; he/she breaks even The expected cost to the firm is the cost of inspection, i.e. the dead weight loss; society loses Al Qaeda won by imposing all the extra costs and inconveniences of defense against attack, on us We have come full circle from the second lecture on “The Impact of Crime On Society”. Terrorism. like crime, imposes the dead weight cost of defense on society. Osama may be gone, but we still bear the cost of his legacy! Our only solace is that he is dead.
