The battle between police and protesters continued in the streets of Seattle yesterday, even after a zone of more than 50 blocks was declared off limits to demonstrators and was surrounded by police, state troopers, King County sheriff’s deputies and the National Guard, many wearing riot gear. About 500 people have been arrested — the final numbers are not yet in — placed in city buses, taken to a relinquished naval facility. Police pepper-sprayed the nonviolent protesters even in buses in which they were being held, this according to the Direct Action Network legal team. Meanwhile, the American Civil Liberties Union yesterday requested a temporary restraining order in a legal action against the city of Seattle. The ACLU order, which was denied, challenged the city’s no-protest zone, which the organization says interferes with the right of people to protest peacefully.
