CHICAGO, IL - AUGUST 28: Chicago Police Sgt. Alan Lasch watches as students arrive at Laura Ward Elementary School on the Westside on August 28, 2013 in Chicago, Illinois. Lasch was posted at the school along with other police officers and city workers to provide "safe passage" to students walking to the school. The Safe Passage program was started because parents were worried about their children’s safety while they walked to school across gang boundaries after the city closed 49 elementary schools and moved the students to nearby schools.
