Joshua Aiken is a writer and legal scholar. He studies how the ordinary machinery of American law — a traffic stop, a gun charge, a suspended license, an asylum claim — decides who is protected and who absorbs harm, and how those decisions come to seem like common sense.
His current research agenda follows guns, and the competing claims of gun control and gun rights, through twentieth-century U.S. law to show how that debate has organized racial distributions of harm—how anti-Blackness structures who counts as an armed citizen and who becomes an armed threat. Three projects are underway.
-
Reasoned Suspicion returns to the years around Terry v. Ohio to show how facially neutral gun laws taught police what suspicion should look like—a history that runs directly into stop-and-frisk, automated license plate readers, and the surveillance systems now making those judgments at scale.
-
Shadow Regime introduces “gun-driven incarceration”, an empirical framework that reconstructs decades of state and federal data to measure how firearm charges and enhancements shaped the growth of American prison populations, a contribution that has gone largely unaccounted for.
-
Armed Authority turns to the 1990s, when the Justice Department armed roughly ten thousand civil immigration officials by administrative rule and Congress handed them warrantless arrest power—an expansion of federal enforcement authority built on the premise that non-citizens are inherently dangerous, and the origin of the armed power now operating in American cities.
