Responses to the event vary. Most people who have actually been exposed to the facts on the NDAA have expressed utter disgust and fury. Rightly so. Some, however, have taken the old elitist mantra, perpetuated effectively by the Neo-Cons in their heyday, that if you are not for the system, then you are a danger to society. Not surprisingly, there are still plenty of useful idiots out there buzzing about like parasites in search of blood.
For those who would applaud these arrests, and suggest that they are well deserved, I would have to ask very pointedly; why?
The bottom line is, it doesn't matter if these activists were in Grand Central Terminal, on the streets, or busting through the doors of the Oval Office. While New York authorities will attempt to argue property loopholes in free speech protections for Grand Central, or national security because of the vulnerability of the terminal, really, this has nothing to do with either. This is about the removal of American voices from a room, and nothing more. If the message is going to be suppressed by the mainstream media, and shrugged off by representatives, then protesters must go to where the people are, and make the truth heard by whatever means necessary.
Ultimately, activism is about disturbing people's normal mundane routines and shocking them out of their pop-culture stupor, even if for a moment. If we aren't allowed to do that without constant police intervention, then the First Amendment is not being served, and then, my friends, we have a problem, a problem which should be forced down the throat of government with even more public action.
