Lie with dogs, wake with fleas.
All the film makers being detained...it was a lot worse in Miami during the the FTAA protests. All dissent was squashed, marchers re-routed, old union people marched a half mile in the heat away from the permitted area, bean bag broke a photographer's skull, people shot up with rubber bullets. Then afterwards, some muckety muck brass with Broward police was videoed regaling his officers with the hilarious recollection of a female lawyer they shot up with rubber bullets after she sassed them by protesting their illegal actions.
All over the country, every large protest is met by immense police suppression. Cops wear black ninja stormtrooper outfits and don't wear name tags. They outnumber protesters. What happened to freedom of assembly, petition, speech? It's just a fiction for the average person.
