Apparently, dancing is a form of "demonstrating".
We will have no demonstrating of your freedoms here!
(slam, slam, slam, slam...)
"On May 28, 2011 Television host Adam Kokesh and several other activists participating in a flash-mob were arrested at the publicly-funded Thomas Jefferson Memorial. Their crime? Silently dancing, in celebration of the first amendment’s champion; a clear violation of their right to free-expression. In an excessive use of force, video was captured of Adam being body slammed and placed in a choke for his non-crime."
