Terrorism, international gangs, and other frequently mentioned national security threats are actually less dangerous than a new type of state-corporate crime that may be called national insecurity crime. This crime poses not only unprecedented victimization, but a massive ethical problem. Examples in the U.S. include the 1980s Savings and Loan (S&L) scandal, the late-1990s dot-com bubble, the 2003 U.S. invasion of Iraq, and the 2007–09 financial crisis. National insecurity crime threatens national security because of its geographic and social extensiveness, severity (...) of harm, dynamism, and unpredictability. It endangers the political, economic, social, and environmental security of most or all of the U.S. population. This endangerment includes increasing the risks of loss, suffering, and destruction on a large scale. This article offers a starting point for a sociological criminology of national insecurity crime. National insecurity crime involves large-scale cooperation that relies on often indirect or mediated interaction between perpetrating persons, groups, and organizations. It also involves widespread social harm for private gain, and yet, due to ideology and social construction, it tends to be hidden in plain sight. (shrink)
