The right to peaceful assembly is just a fantasy. So is the belief that you have rights. What we really have now is a fascist oligarchy, it is not being governed as a Constitutional Republic. President Eisenhower's famous last speech has become a reality, especially the phrase "beware of the military industrial complex". The Ludlow massacre was perfect example of military industrial complex crime. And no one was ever really punished for it.
