In SuperFreakonomics, we catalogued some of the collateral costs of the 9/11 terrorist attacks, including roughly 1,000 extra traffic deaths in the U.S. in the three months after 9/11, the result of so many people driving instead of flying:
Such trickle-down effects are nearly endless. Thousands of foreign-born university students and professors were kept out of the United States because of new visa restrictions after the September 11 attacks. At least 140 U.S. corporations exploited the ensuing stock market decline by illegally backdating stock options. In New York City, so many police resources were shifted to terrorism that other areas — the Cold Case Squad, for one, as well as anti-Mafia units — were neglected. A similar pattern was repeated on the national level. Money and manpower that otherwise would have been spent chasing financial scoundrels were instead diverted to chasing terrorists— perhaps contributing to, or at least exacerbating, the recent financial meltdown.
The Wall Street Journal now reports on a most unlikely unintended consequence of the attacks and the ensuing hunt for Osama bin Laden:
The United Nations says a reportedly fake vaccination campaign conducted to help hunt down Osama bin Laden has caused a backlash against international health workers in some parts of Pakistan and has impeded efforts to wipe out polio in the country. A number of families across Pakistan refused vaccinations from July, when news of the reportedly fake campaign broke, to September, said Dennis King, chief of polio vaccinations in Pakistan for Unicef. “Following the early reports, some families in the provinces did refuse to have their children vaccinated citing the fake campaign as the cause,” Mr. King said. … The issue has given fresh ammunition to Islamist preachers who for years have claimed foreign health workers are spies and urged people to shun vaccination campaigns.
