Despite already making 180 arrests, Toronto police are preparing for even more protests Sunday outside the G-20 summit talks. “I do not believe that the individuals bent on vandalism and violence in our city have finished with their intent,” the city’s chief of police said Saturday night, noting that much of the violence—including four burned police cars—is coming from a small group of disruptors infiltrating a largely peaceful crowd. Still, the police dispatched pepper spray, tear gas, and bean bag pellets in attempts to diffuse the protesters. Meanwhile, inside the meetings, leaders plan to address the competing needs to nurse recovering economies and reduce large budget gaps. “This summit must be fundamentally about growth, and our challenge…is that we all need to act to strengthen the prospects for growth,” U.S. Treasury Secretary Timothy Geithner said.
