The Mayor of Oakland has asked courts to throw any Occupy activist with a record of protest arrests out of the city. Her demand follows one of the most dramatic clampdowns on the movement in its history. More than 400 people were arrested when what began as a peaceful rally against inequality and police brutality turned rough. Riot clad cops jumped into action - firing volleys of tear gas and flash grenades at protesters hiding behind makeshift barriers bearing peace symbols. First-hand accounts say that police were carrying lists of demonstrators with them, which they used to arrest attendants. Sara Flounders, from the International Action Center, believes the Occupy movement is like an alarm clock for a dying American dream.
