Chicago’s murder rate is higher than some other big cities, but according to Chicago Police Supt. Jody Weis, the last time it was this low in the city, Mayor Daley’s father was mayor and Lyndon Johnson was president.

Aggravated assault was down 12 percent, robbery 11 percent and sexual assault down 9 percent. “3,400 fewer incidents overall from last year,” Weis said at a news conference on Monday. Car theft, however, was up 22 percent. There weere 435 murders in 2010, Weis said, and more than half were solved.
