Liberdade sim, mas com juizinho, parcimónia, e na devida conta:
Free Speech Zone
Free speech zones (also known as First Amendment Zones, Free speech cages, and Protest zones) are areas set aside in public places for political activists to exercise their right of free speech in the United States. The First Amendment to the United States Constitution states that "Congress shall make no law... abridging... the right of the people peaceably to assemble, and to petition the Government for a redress of grievances." The existence of free speech zones is based on U.S. court decisions stipulating that the government may regulate the time, place, and manner—but not content—of expression.
The most prominent examples are those created by the United States Secret Service for President George W. Bush and other members of his administration. While free speech zones existed in limited forms prior to the Presidency of George W. Bush, it has been during Bush's presidency that their scope has been greatly expanded.
