The most basic component of freedom of expression is the right of freedom of speech. The right to freedom of speech allows individuals to express themselves without government interference or regulation. The Supreme Court requires the government to provide substantial justification for the interference with the right of free speech where it attempts to regulate the content of the speech. Generally, a person cannot be held liable, either criminally or civilly for anything written or spoken about a person or topic, so long as it is truthful or based on an honest opinion, and such statements.
A less stringent test is applied for content-neutral legislation. The Supreme Court has also recognized that the government may prohibit some speech that may cause a breach of the peace or cause violence. For more on unprotected and less protected categories of speech see advocacy of illegal action, fighting words, commercial speech and obscenity. The right to free speech includes other mediums of expression that communicate a message. The level of protection speech receives also depends on the forum in which it takes place.
Despite popular misunderstanding the right to freedom of the press guaranteed by the First Amendment is not very different from the right to freedom of speech. It allows an individual to express themselves through publication and dissemination. It is part of the constitutional protection of freedom of expression. It does not afford members of the media any special rights or privileges not afforded to citizens in general.
