Pittsburgh city council CANNOT pass ANY laws or ordinances concerning firearms . PA has a Constitutional preemption clause that prohibits such actions.
I think you are misinformed.
I would love to be corrected on this.
I believe they have a preemption law, but it has no teeth, no way to force compliance.
A statute with teeth was passed a couple of years ago, and signed into law; but a corrupt AG (she went to prison) and cities took it to court and had the law thrown out on an almost never used technicality.
The end result was the cities (particularly Philadelphia) simply ignore the law, and pass illegal ordinances.
