PITTSBURGH - The city has a new law that would fine or jail gun owners who do not report stolen or missing guns within 24 hours.

Mayor Luke Ravenstahl allowed the bill to become law yesterday when he returned it to Council without his signature. Ravenstahl said that he does not believe the measure will be enforceable and that it will be preempted by state law, but that he appreciates the effort to reduce gun violence.

Some Council members said they realize the measure may be illegal, but feel they must do something to address a rash of recent gun violence in the city.

The state's supremacy on gun laws also has been challenged in Philadelphia, where a similar measure was signed by Mayor Nutter.
