If that was taken from the 'Occupy Wall Street' demonstrations, and the arrests the NYPD was making, then I'm totally on board with the Marine. Peaceful protests are protected under the Bill of Rights, something that seems to be forgotten, especially when the ultra wealthy want the 'eyesore' removed.
How does he know the cops he was yelling at were involved? That would be like me yelling at him for what happened at Guantanamo Bay. There was nothing peaceful about what he was doing. He made it very clear he was ready to get violent.
Just watching the backgrounds in the video, the cops were there doing something, and based on time frame the OWS would fit. You don't get large groups of cops just standing around for no good reason.
And no point did I think the Marine was threatening violence. Loud does not equal violence. Nor does calling someone else a coward.
He has spend time in the service defending the nation he loves, and clearly felt the rights that he put his life on the line for were being infringed upon by the police. And from what I have seen in the news, he would be right.
