Abstract
This article criticizes recent proposals for covert government operations against conspiracy-theory groups and networks. The article argues that fear of secret plots by political insiders is intrinsic to America’s civic culture, legal traditions, and political institutions. The appropriate government response to conspiracy theories is not to try to silence mass suspicions but instead to establish procedures for ensuring that suspicious events are thoroughly and credibly investigated. As it stands, investigations of assassinations, defense failures, election breakdowns, and other political events with grave implications for America and the world fail to meet basic standards for transparency, independence, and objectivity.
