The restrictions came after a federal court order in January forced Chicago to end its ban on gun sales in the city and gave officials until July to put in place regulations before the ban is lifted.
The Emanuel administration in a report released this week makes a case for Chicago gun shops to videotape all sales, ban gun shops in 99.5% of the city and limit each gun buyer at a store to one purchase a month, except for relics and returns. Gun sellers would be subject to quarterly audits.
In addition, gun shop workers would have to pass background checks and be trained to spot fake or "straw" purchasers, such as a male gang member getting a girlfriend to buy his gun because he's ineligible.
Attempting to deter shops from making sketchy sales, city officials could cross-check records against a regional trace database that Emanuel wants to establish, showing where guns used in crimes were purchased. Fines for violations could run a few thousand dollars.
A study released last year by
Still, the researchers said that the result was "consistent with a growing body of research evidence which indicates that gun dealers' sales practices affect the probability of guns getting to criminals and that policies designed to hold gun sellers accountable can curtail the diversion of guns to criminals."
During the last five years, 20% of guns used in crimes in Chicago were bought from four shops just outside the city, according to this week's report.
For example, Chuck's Gun Shop in
Officials at all four stores declined to comment.
Two buyers — one in Georgia and one in Indiana — bought 33 of the thousands of guns used in Chicago crimes during that period.
Though Chicago's rules might not choke off such suppliers, the mayor said he intended to make sure his city didn't become a source of illicit guns.
"Now that we're required to allow gun sales within the city limits, we do it in a way that does not undermine our public safety goals," said Emanuel, speaking at the Police Department's annual awards ceremony on Wednesday. He called the proposal "smart," "enforceable" and one of the toughest in the country. But gun rights groups, who have challenged Chicago gun laws for years, could go to court to stop the latest effort if it passes the City Council.
A city report showed that 13 people out of every 100,000 in Chicago died because of guns in 2011, while 6 per 100,000 died in Los Angeles and 4 per 100,000 in New York as a result of firearms.
Also this week, a lawmaker in Massachusetts introduced legislation to strengthen what is already one of the country's strongest limits on gun buying.
The measure would require all sales to take place in the presence of a licensed dealer. Police would also have the authority to reject rifle and shotgun sales to "unsuitable" buyers instead of just handgun sales. Massachusetts House Speaker Robert DeLeo said that in determining suitability, police would be ensured access to all public court records about prospective buyers' criminal, mental health and substance abuse records.
