Shell Icebreaker Retreats After Showdown With Protesters

A Shell Oil icebreaker retreated Thursday after a showdown with environmental activists dangling from Portland, Oregon's tallest bridge. Protesters on St. Johns Bridge and kayakers on the Willamette River below have been blocking the icebreaker from heading to the Arctic for a drill operation. The U.S. Coast Guard warned the danglers they were breaking the law, but took no action. Petty Officer 1st Class George Degener said the agency did not tell those aboard the icebreaker to turn around. "I don't know what led the master and the pilot on board to come to that decision," he said.
