Oakland prepares for possible property destruction during May Day gatherings By Andre Torrez article OAKLAND, Calif. - The City of Oakland issued a letter on Thursday in anticipation of this Saturday’s May Day gatherings that warned residents and businesses about potential planned mayhem. City officials said that aside from planned peaceful events commemorating the struggles of workers and the labor movement, there may be more sinister plans in the works. "It has been brought to our attention that others may be intending to deliberately cause property damage, violence, and destruction in our city," City Administrator Ed Reiskin wrote. Residents and business owners are encouraged to install security systems and remove garbage cans, flower pots and other unsecured objects, Reiskin's letter said.
