Sounds like things are getting dicey in the battle over the Santa Monica ficus trees. About 60 people showed up yesterday at Santa Monica City Hall to hold a peaceful sit-in, Jerry Rubin, founder of Treesavers, tell us. He says that a few of the Treesavers are now doing a 24-hour watch for trees--with some people sitting in cars-- to watch the trees and ensure they aren't cut down. "We hope we don't have to resort to non-violent defense, where people would sit in the trees, or chain themselves to the trees," says Rubin. "That isn't what we want. " Also, the group's attorney plans to file an emergency stay of appeal of the judge's ruling last week that essentially paved the way for the trees to get cut down.
