Remember 'Bro' (from the post below?) A number of people complained that him being denied the opportunity to take his non-sensical, directionless rant disguised as a question with a preface to the never-ending lengths to which he strived was an infringement of his right to free speech (as given to him in the bill of rights).
Lets clarify exactly what the 1st Amendment says and means...

Amendment I
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

So... the government shall not make a law keeping any citizen from speaking their mind.
Well, it hasn't. Anyone is still free to say whatever they want in a public forum. Of course there are some common sense guidelines that apply to this.
For example: One can't yell "fire!" in a crowded movie theatre. One can't level threats to other individuals. One can't lie to a police officer or file false police reports.
The idea behind amendment #1 is that because we are a government of the people, by the people, for the people the government won't restrict what the people say about the government. Our collective and individual voices will not be impeded.
But that right doesn't supersede every other right and law in existence. In other words: One can not break into someone's house and start making a speech on the dangers of free economy. You still broke into someone's house! Just because you're yapping away during your breaking and entering doesn't nullify the fact that you broke and entered.
Whatever point 'Bro' was thinking he was getting to while at the microphone, he was still on private property at a limited seating function and his attendance was a privilege granted to him not a right. He was still bound to conduct himself by the guidelines set by those conducting the event.
If 'Bro' had chosen to cooperate with police he would have been free to continue his ramblings out on the sidewalk... as our forefathers intended us to be able to do.

So, again... a note to those up in arms that 'Bro's' rights were violated. They were not. No one stopped him from saying what he felt like saying. The organizers of the event simply wanted him to stop saying it in their private forum. Much like all of you would want someone to stop screaming on your doorstep at 1 o'clock in the a.m.

As Joe Strummer and The Clash says: Know Your Rights... beofore you bellyache that they've been violated.
