This course surveys the freedoms of speech, press, and association as developed under the First Amendment. Representative topics include: the theoretical justifications for the freedom of speech; whether and when the government may punish defamation, true threats, obscenity, and similar categories; limits on protests and the use of public forums; free speech in K-12 education; and the First Amendment’s application to crucial technological phenomena such as social networks, AI, and online mis- and disinformation. After this course, students should have an understanding of the core free-speech doctrines of the First Amendment, the ability to assess and critique those doctrines, and the ability to apply such doctrines to novel technological or political contexts.
