of Oakland was again shut down as Occupy Oakland protesters participated in a West Coast shutdown of ports. At the Port of Oakland, hundreds of protesters stayed overnight and successfully stopped the 3AM shift of ILWU workers from entering the Port to work. The crowd eventually dispersed peacefully with no arrests or even police presence. Anti-police Saturday evening marches of 2012 Starting the first Saturday of January, some supporters of Occupy Oakland began a series of what they called "Fuck The Police" (FTP) protests. Officials estimated that policing each FTP in January cost the City about $50,000.
