Protests are expected throughout this week's Asia-Pacific Economic Cooperation leaders’ conference, which could draw more than 20,000 attendees, including hundreds of international journalists. San Francisco has a long tradition of loud and vigorous protests, as do trade talks. In 1999, tens of thousands of protesters took to the streets of Seattle during a World Trade Organization conference. San Francisco Police Department Chief Bill Scott said he expects several protests a day, although it's uncertain how many will materialize. “People are welcome to exercise their constitutional rights in San Francisco, but we will not tolerate people committing acts of violence, or property destruction or any other crime,” Scott said.
