German shows that any ideology can be targeted if the national security bureaucracy comes to use activism as a proxy or precursor for crime and terrorism:
A Texas fusion center warned about a terrorist threat from “the international far Left,” the Department of Homeland Security and a Missouri fusion center warned of threats posed by right-wing ideologues, and a Virginia fusion center saw threats from across the political spectrum and called certain colleges and religious groups “nodes of radicalization.” These are all examples of domestic security gone wrong.
“Gone wrong” means weak in theory, threatening to liberty, and not helpful to law enforcement:
If these “intelligence” reports described recent crimes and the people who perpetrated them, there would be little problem from a civil rights perspective, and it could actually be helpful to the average police officer. Instead, they have followed a “radicalization” theory popularized by the NYPD (PDF). That theory postulates that there is a “path” to terrorism that includes the adoption of certain beliefs, and political, religious, or social activism is viewed as another step toward violence. Actual empirical studies of terrorism conducted in the Netherlands and Britain refute this theory, but the idea that hard-to-find terrorists can be caught by spying on easy-to-find activists appears too hard to resist to U.S. law enforcement.
The takeaway: “Threat reports that focus on ideology instead of criminal activity are threatening to civil liberties and a wholly ineffective use of federal security resources.”
