How Post-9/11 Fear Fueled a Lasting Expansion of U.S. Surveillance
The article argues that the terror attacks of September 11, 2001 sparked a permanent growth in U.S. government size and surveillance powers that persists 25 years later.
The piece recounts how the September 11 attacks prompted a sweeping reorganization of the U.S. government, culminating in the 2003 launch of the Department of Homeland Security and the formation of agencies like the TSA, ICE and the Office of the Director of National Intelligence. Federal spending on defense and security surged, and the USA PATRIOT Act dramatically loosened limits on wiretaps, data collection and information sharing.
These changes introduced ubiquitous surveillance tools—from airport facial scans to local police license-plate readers and drone deployments—often justified as counter-terrorism measures. While some early initiatives, such as certain passenger-risk-scoring systems, were later abandoned, the majority of expanded powers persist, exemplifying a “ratchet” dynamic in which crises produce lasting governmental growth. The author cites Edward Snowden’s revelations and Robert Higgs’s theory to illustrate how fear reshapes public acceptance of intrusive policies. Ultimately, the article warns that defending liberty requires ongoing citizen vigilance against the lingering encroachments born of 9/11.
