There is a very good write-up on the police riot of Genoa in the Guardian;
"There are several good reasons why we should not forget what happened to Covell, then aged 33, that night in Genoa. The first is that he was only the beginning. By midnight on July 21 2001, those police officers were swarming through all four floors of the Diaz Pertini building, dispensing their special kind of discipline to its occupants, reducing the makeshift dormitories to what one officer later described as "a Mexican butcher's shop". They and their colleagues then illegally incarcerated their victims in a detention centre, which became a place of dark terror....Genoa tells us that when the state feels threatened, the rule of law can be suspended. Anywhere."
We should also not forget how much of the media just climbed on-board with the faked police account of what happened. I single out the Daily Mail & it's 'journalist' Lucie Morris as the worst. But the deeper meaning in the article holds true. When the state feels threatened, than and and all means become available;
"No government fights fascism to destroy it. When the bourgeoisie sees that power is slipping out of its hands, it brings up fascism to hold onto their privileges."Buenaventura Durruti
It is worth remembering this are we move into the age of the end of oil.
