How the rise in violent crime is affecting college campuses

As violent crime surges in cities big and small across the country, it is encroaching on what many have considered safe havens — college campuses, which are having to step up safety protocols in response. 

The Chicago area has seen more than 1,000 homicides this year, according to Cook County Government. Three victims were University of Chicago students or recent graduates who were gunned down near the school this year. 

Philadelphia broke its previous homicide record that was set in 1990, with 524 this year, according to the city's police department. Several of the murders occurred near Temple University, including that of student Sam Collington who was recently killed by an alleged carjacker.
