Chicago's ban on gun sales was struck down as unconstitutional

Chicago Mayor Rahm Emanuel has proposed an edict that would bar gun shops from operating in 99.5% of the city and require video of each sale.

The proposal comes in response to a court order overturning the city's ban on handgun sales.

Chicago has some of the strictest gun laws in the US and a gun-related murder rate three times higher than New York's and twice Los Angeles's.

Some city leaders expect this latest plan to be challenged in court.

The package of measures includes:

• videotaping of all sales in gun shops
• prohibit gun sales within 500 feet of schools or parks
• limiting sales to one per month per buyer
• a 72-hour waiting period to buy handguns, 24 hours for rifles and shotguns
• gun store employees to undergo background checks

When asked whether videotaping sales amounted to intimidation, Mr Emanuel said cash withdrawals were also on film.
