Vandals continue to spray-paint anti-Semitic slogans and other offensive graffiti in a Toronto neighborhood despite cleanup efforts by volunteers. The vandals have left threatening notes and thrown rocks through the windows of local residents who have removed the graffiti from garage doors and other spaces. "Figuratively speaking, the perpetrators have said, 'Oh yeah?' and it's escalated, it's a war now," said Police Superintendent Paul Gottschalk, who has tripled police patrols in the east Toronto neighborhood. Gottschalk said the graffiti is likely not the work of gangs. He noted that two lanky teens were seen hanging around a school that was spray-painted. "I'll bet you it's someone living right around the corner," he said.
