Chicago's gun control response to the McDonald ruling

This AP story, which is headlined "Mayor Daley lays out strict gun rules for Chicago," provides the new sure-to-be-challenged gun regulations that Chicago has in the works now that the Supreme Court has made clear that it has to comply with the Second Amendment:

With the city's gun ban certain to be overturned, Mayor Richard Daley on Thursday introduced what city officials say is the strictest handgun ordinance in the United States.

The measure, which draws from ordinances around the country, would ban gun shops in Chicago and prohibit gun owners from stepping outside their homes, even onto their porches or garages, with a handgun....

"As long as I'm mayor, we will never give up or give in to gun violence that continues to threaten every part of our nation, including Chicago," said Daley, who was flanked by activists, city officials and the parents of a teenager whose son was shot and killed on a city bus while shielding a friend.

The ordinance, which Daley urged the City Council to pass, also would:

• Limit the number of handguns residents can register to one per month and prohibit residents from having more than one handgun in operating order at any given time.
• Require residents in homes with children to keep them in lock boxes or equipped with trigger locks.
• Require prospective gun owners to take a four-hour class and one-hour training at a gun range. They would have to leave the city for training because Chicago prohibits new gun ranges and limits the use of existing ranges to police officers. Those restrictions were similar to those in an ordinance passed in Washington, D.C., after the high court struck down its ban two years ago.
• Prohibit people from owning a gun if they were convicted of a violent crime, domestic violence or two or more convictions for driving under the influence of alcohol or drugs. Residents convicted of a gun offense would have to register with the police department.
• Calls for the police department to maintain a registry of every handgun owner in the city, with the names and addresses to be made available to police officers, firefighters and other emergency responders.

Those who already have handguns in the city — which has been illegal since the city's ban was approved 28 years ago — would have 90 days to register those weapons, according to the proposed ordinance.

Residents convicted of violating the city's ordinance can face a fine up to $5,000 and be locked up for as long as 90 days for a first offense and a fine of up to $10,000 and as long as six months behind bars for subsequent convictions.

Perhaps readers can share their views as to which of these proposed regulations seem most likely to withstand or wither under a Second Amendment attack based on Heller and McDonald.
