In the wake of the 9/11 attacks, the U.S. government expanded its domestic police powers on the grounds of protecting the person, property, and liberties of U.S. citizens. Many of these expanded police-state powers persist today. This paper explores how a constitutionally constrained democratic government can take on police-state powers that sustain themselves over time and catalogs some police-state powers implemented after the 9/11 attacks that have persisted—including surveillance activities, militarization of the police, civil asset forfeiture, expanded border patrol, and the no fly list.
