When there are a million protesters there is no need for disorderly conduct. But when there are only a few hundred no one pays attention without some hell-raising.The purpose of a protest demonstration is to call attention to an issue.
The advertising industry has established that with few exceptions the more annoying a radio or television commercial is the more effective it ultimately will be because it calls attention to a product which otherwise would remain obscure. Complying with the rules laid out by the power establishment to regulate public protest demonstrations would be completely counterproductive. Consequently, for a demonstration to be effective the participants must be willing to subject themselves to arrest.
So they should have gotten a permit, then they could have called attention all they wanted..the police would have shut the street down for them to do so...they didn't have a permit thus they violated the law. Actually no an effective demonstration does not mean you have to subject yourself to arrest let me show you what an effective demonstration and peaceful one was..not a single person was arrested....over 1 million marched..
You can't seem to understand that the squeaky wheel gets the grease.
That is exactly how the few did it and has gotten to the few extreme far left (liberals) ruling the many (moderate to conservative).
