Occupy Portland is making waves again. Police in the Oregon city arrested more than 50 people while clearing the encampments of the Occupy movement on Sunday. Authorities issued an eviction notice, and officials then moved to clear the camps and fence them off. Portland’s Mayor Sam Adams said the city's camps had been linked to an increase in crime and drug overdoses, and said that while he was sympathetic to the protest's goals, the Occupy movement should move beyond encampments "in order to get the reforms we need." In Oakland, Calif., police have warned of a similar crackdown.
