James Alan Fox, a criminologist at Northeastern University in Boston, noted that homicide levels in Chicago have generally been declining over the past decade.
Still, he said, police have difficulty preventing homicides despite their best strategies.
“I don’t think you can change the unemployment rate through the police. It’s really hard to have an impact on the flow of illegal guns,” he said.
Even with the improved numbers, Chicago remains far ahead of other big cities with its number of homicides so far this year. New York City has had 240 slayings and Los Angeles has 203, according to police statistics from late September, the most recent numbers available for the two cities. As of Thursday, Philadelphia had recorded 189 slayings.
