Protesters marched down Seattle's streets Tuesday afternoon, many dressed in black clothes and wearing face makeup, as part of annual May Day demonstrations.
Some windows in downtown were broken and there have been a handful of arrests. Still, whether anarchists or violent protesters may later outnumber the peaceful groups remains to be seen. A few protesters have been arrested.
The group of more than 100 protesters left Seattle's Westlake Park and wandered through the streets, carrying banners, waving flags, holding signs and disrupting traffic.
In addition, a large number of students walked out of Seattle Central Community College, gathering for a march down Capitol Hill.
Speeches and concerts continued at Westlake Park, where protesters remained peaceful. A group called "Hip Hop Occupy Seattle" called for the crowd to protect each other.
Protesters are being flanked by Seattle Police officers on bicycles. The Seattle Police Department said they plan to put extra officers in place at demonstrations, both in uniform and undercover.
Mayor Mike McGinn and other city leaders said they remain concerned that anarchist groups may turn to violence at the normally peaceful protests.
Signs and websites have been found advocating Seattle's protesters to "strike back" or "shut down the city."
Seattle May Day organizers said they have their own security forces. Both Occupy Seattle and El Comite will have a group of "peacekeepers" in the crowds working with police.
The Occupy Movement is also placing "peacekeepers" within their march from Seattle Central Community College to Westlake Park. They too said they ask troublemakers to stay away.
Seattle Mayor Mike McGinn is scheduled to be at the El Comite demonstration at 6:30 p.m. He plans to tell them about his support of immigration reform.
