Chicago police car

Chicago experienced a 58 percent increase in homicides and 43 percent more non-fatal shootings in 2016, according to a University of Chicago Crime Lab report. While annual spikes "of this size are not unprecedented among American cities," they are unusual for a city of Chicago’s size, according to researchers at the Crime Lab, which MacArthur supports. The study found that violence was concentrated in a moderate number of the city’s most disadvantaged neighborhoods, and generally carried out by teens and young adults in public places with illegally owned guns.
