Security and Freedom After September 11

Preventing terrorism is a high priority after September 11, but few studies have investigated the limitations and costs of prosecuting suspects under antiterror laws. This article examines PATRIOT Act oversight and its relationship to prosecutions. Three topics are analyzed—the Act's origins and oversight provisions, along with major criticisms; trends in antiterrorism prosecutions and convictions; and inspector general oversight of the act—together with the ethical implications of using antiterror laws in ordinary criminal prosecutions.
