I guess, it's the fact they didn't ask for permission first...Not like they would get it anyways...People just don't want to hear about the problems, they would rather hide their heads in the sand and let the machine roll on, while they wait for the next episode of American Idol...It's far easier to say those hippys don't know what they're talking about, than to accually listen and think about it. Using your brain just takes way too much effort, they want to be told how to think and then tell others their view point is right.
I don't think your statement is 100% accurate. I think people who give two shakes do want to know, hear, learn, and understand, they do not want, expect, or deserve for that matter to be subjected to the in your face disorderly tactics that were used by this group.
If you want to gather a group and go scream at city hall, in my opinion is one thing, those are folks that are paid by you, make decisions on your behalf, and when they screw up should hear from you LOUD AND CLEAR. However the average citizen, no matter what their agenda or motive is not beholden to hear your message, they may want to but should be able to do so on their terms... not yours.
Perfect example: Any small town festival held in the huge city park during the summer. Go to any and normally you will find some politically minded, issue charged group with a booth set up and runners handing out paphlets about their issue. If you want to hear or read about what they have to say you stop or take and read. If that group decides just to start yelling and screaming at the entire attending public they do and should get arrested for disturbing the peace... and ruining everyones day. Forcing your voice on a semi captive audience, and assuming it is OK to do so because they care more about American Idol, is a much more dictitorial avenue than actually being arrested for doing it. IMHO.
Ah see they do have permission. The first amendment. I guess you had better use them before you lose them too.
The First Amendment:
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....
Now I am assuming the highlighted text is what we have in mind here.
If you can prove that this groups message was the reason they were arrested I will grant you an EZ win here. Read on.... peaceably assemble.... to assemble in peace. I don't think trapping hundereds on a subway platform and forcing them to listen to that punk girls loud trap qualifies. Most likely they were arrsted for public order type crimes (i.e. disturbing the peace, failure to follow a lawful order, or if the platforms are privately owned trespassing) but I guarandamtee you they were not arrested for what they were saying.
