Criminal speech is a legal concept that identifies certain kinds of speech as a crime. The concept is somewhat at odds with freedom of speech in its broadest sense, within the broader freedom of expression, and asserts certain limitations on such freedom.
Concepts like criticism of government and criticism of royalty are controversial. Other concepts limiting certain kinds of speech are not, such as that which prohibits shouting fire in a crowded theater (as a practical joke, and not as a warning), as such speech has the potential to cause harm.
Laws vary by country according with the legal principles that such country adheres to. Most speech is unregulated, and does not violate law. In reference to authoritarian governments which assert serious controls, such controls are commonly called suppression of dissent. In democracies, the concept of hate speech has emerged in recent years, to counteract the political and social influence of hate groups.
Famous quotes containing the words criminal and/or speech:
“It could probably be shown by facts and figures that there is no distinctly native American criminal class except Congress.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Lying increases the creative faculties, expands the ego, lessens the friction of social contacts.... It is only in lies, wholeheartedly and bravely told, that human nature attains through words and speech the forebearance, the nobility, the romance, the idealism, that—being what it is—it falls so short of in fact and in deed.”
—Clare Boothe Luce (1903–1987)
