Men who are not police force a protester into a car and drive off in Pittsburgh

These are not police. They are wearing camouflage, NOT police uniforms. The vehicle that this protester is wrestled into (without being read any rights or any other statements) is NOT a police car.

There were certainly scuffles between police and protesters around the G-20 summit in Pittsburgh today but this 'arrest' (I don't know if you could call it that) is something new, something sinister.

Paramilitary squads now operating openly in the United States. Keep in mind that in other countries in the not-so-distant past, paramilitary squads did things the police could not do, including torture, murder and 'disappear' people.

I don't know if this was a leftist or a rightist protester, nor do I know who sent out the goon squad or what their agenda is. It doesn't matter. If they can do this to him, they can do it to you or to me.

UPDATE: Some chatter around the internet suggests that these MAY be members of the Pennsylvania National Guard. If they are and are operating under federal authority then that would be a clear violation of the Posse Comitatus Act, which prohibits the use of federal troops (including federalized national guard) to conduct police operations within the United States. If they are national guard troops and if they were operating under the direction of Governor Ed Rendell then they have the legal right to act, but the method of arrest in which the protester was not read his rights and was wrestled into a car which then departed for an undisclosed location is still of questionable legality.
