Mayor Rahm Emanuel on Sunday told more than 1,000 people that good parenting and aggressive policing are key to solving Chicago's gun violence problems.

At the annual conference for the Council on Foundations, a nonprofit association of more than 1,700 foundations, Emanuel said police officers will be saturating high-crime areas of Chicago, and the city will help expand a mentoring program for young minority men.

"I say it's the four P's … policing, prevention, penalties and parenting," he told the crowd as they ate lunch at the Hilton Chicago. "You're going to be as strong as the weakest link in that chain."

Emanuel was joined on a three-person panel by Philadelphia Mayor Michael Nutter and New Orleans Mayor Mitch Landrieu, who spoke about the societal and cultural challenges facing their cities.

They said they have focused on illegal guns and partnering with foundations and community resources to curb the culture of violence. The mayors also called gun violence a national problem.

Emanuel cited a city-issued study that shows where most crime — like robberies, shootings and homicides — takes place as one possible prevention method.

The findings showed those crimes largely occurred in 20 zones that represent about 4 percent of Chicago's geographical area but account for 25 percent of the city's violence, he said.

To combat those numbers, the Police Department will start foot patrols in those areas from 6 p.m. to 2 a.m., Emanuel said.

"We will be saturating the worst areas," he said.

Besides policing, the city is doubling the number of spots in its summer job program to 1,500 and working with the University of Chicago Crime Lab to expand Becoming a Man, a mentoring and behavioral skills program, from 2,000 participants to 4,000, Emanuel said.

"You give me 10,000 active, involved fathers in kids' lives, then you can reduce everything we're talking about with the saturation of policing," Emanuel said.

The mayor also touted the 50 percent drop in homicides for the month of February and the 69 percent reduction in March.
