Abstract
In recent years American legislatures and other governing bodies, public and private, have been considering, probably more frequently than ever before, problems associated with the idea of overthrow of government by force and violence. The question usually takes the form of whether Communists believe in and advocate this doctrine; and, if they do, whether they should therefore be penalized in various ways. This issue is and has been central to a series of legal actions which, whatever their ultimate outcome, will constitute a landmark in the history of American jurisprudence.
