Philadelphia Ignores State Law, Passes Five New Gun Laws

The Philadelphia Inquirer notes:

The five laws - called everything from unconstitutional to criminal by critics - do the following:

Limit handgun purchases to one a month.

Require lost or stolen firearms to be reported to police within 24 hours.

Prohibit individuals under protection-from-abuse orders from possessing guns if ordered by the court.

Allow removal of firearms from "persons posing a risk of imminent personal injury" to themselves or others.

Outlaw the possession and sale of certain assault weapons.

Nutter said he would begin to enforce the laws immediately, with the exception of the one-gun-a-month requirement, which takes effect in six months.

He and Council are in for a fight, however. The city has tried and failed for three decades to buck the 1974 state law that reserves gun regulation to the state legislature. The state's preeminence appeared to be cemented in a 1996 Supreme Court ruling that allowed the legislature to prevent Philadelphia and Pittsburgh from enacting local gun laws. . . . .

One question: Can Nutter or anyone else point to one single study by economists or criminologists that show that any of these gun control laws reduce crime? Just one single study?
