Mayor Daley Preps For Supreme Court Gun Ban Ruling.

If the high court overturns ban, he said he's ready to jump into action. Reporting Suzanne Le Mignot CHICAGO (CBS) ― Forty-eight hours from now, the Supreme Court could overturn Chicago's handgun ban. Mayor Daley says he's ready to act if that happens, as CBS 2's Suzanne Le Mignot reports.

The mayor said legislation would immediately be introduced in City Council. He said the violence last weekend, 54 people shot, 10 of those people dead, shows the need for the city's handgun ban to remain in place. The mayor also said, taking control of the violence starts with residents, taking a stand.

Members of New Life Covenant Church and other organizations lined 79th Street, from Dobson to the Dan Ryan Expressway, asked God for mercy on their community -- 3,000 strong with heads bowed.

"There's power in numbers and we outnumber any gang banger, any drug dealer or anybody with guns," said Pastor John Hannah of New Life Covenant Church.

Their message, wanting gun violence to end in the city, is not lost on Mayor Daley.

Monday, the Supreme Court is expected to issue their ruling on Chicago's handgun ban. There's speculation, the ban will be overturned. Daley said legislation would immediately be introduced in city council.

"Guns are not the answer. Like in a home or outside a home, to solve all the issues confronting people. If allow it, if you allow guns to overtake us, they will overtake you," Daley said.

"I'm still optimistic they're not gonna overturn it. I think it's getting into the state's ability to govern themselves, but we'll be prepared for that," said Chicago Police Supt. Jody Weis. "We've discussed a lot of options, but we really can't move too far forward, until you really know what you have. The challenge is, once they make this decision, it's in effect immediately."

Weis on Friday announced that Ernest Brown, the chief of the organized crime division, was promoted to Deputy Superintendent of the Patrol Division, replacing Dan Dugan. But Saturday, Weis said he changed the leadership of his department's patrol division to inject a shot of innovation and bolster officers' ability to forge bonds with community residents to tackle the gang problem and fight crime across the city.

Ronald Holt lost his son Blair to gun violence in 2007. Holt is now the Director of the CAPS (Community Alternative Policing Strategy) program for the city.

"Well of course we hope that the Supreme Court does not overturn the ruling because the handgun ban in Chicago is still a tool in the shed, not just for the Chicago Police Department, but for the community as well," Holt said.

Like Blair Holt, Joyce Hunter's son, Julius Birdine was also shot to death in 2007. Hunter said the Supreme court overturning the city's handgun ban, would mean only one thing.

"More killing. More killing. More killing. And it needs to stop. It needs to stop. We need to save our youth," Hunter said.

So does Walter Jacobson.

When it comes to the safety of young people in the city, the mayor announced a number of new programs, among them, one connecting curfew violators with positive activities and mentoring.
