Dancing is not considered a form of free speech, at least not when it’s being done at the Jefferson Memorial. After being arrested for gyrating along with some friends at the monument in April 2008, Mary Brook Oberwetter, 28, filed a lawsuit against the National Park Service. Oberwetter and 17 others had gathered at the memorial on the eve of Thomas Jefferson’s birthday and began dancing “for the most part by themselves, in place, each listening to his or her music on headphones” because such activity expressed “the individualist spirit for which Jefferson is known.” Park service police told them to stop. When Oberwetter refused, she was thrown in jail for demonstrating without a permit.
