Which of the following is NOT listed as a non-public forum?

• A. Jails
• B. Airport terminals
• C. Courtrooms
• D. Public Park

Answer: (D)

Non-public forums are government spaces not traditionally open to public expression, where speech can be restricted to serve the forum’s purpose. Jails, courtrooms, and airport terminals are treated as non-public forums because their primary functions require order and security, so rules about what can be said or displayed can be reasonable and viewpoint-neutral. A public park, on the other hand, is a traditional public forum where open discussion and assembly have long been encouraged, so speech restrictions there must be content-neutral, narrowly tailored, and provide ample alternative channels. Since a public park is not a non-public forum, it is the option that does not belong in that category.
