PITTSBURGH (AP) — The city of Pittsburgh plans to appeal a judge’s ruling that it can’t enforce gun laws passed in the wake of the synagogue massacre. A spokesman for Democratic Mayor Bill Peduto says the city expected a long legal battle and “will continue to fight for the right to take commonsense steps to prevent future gun violence.” An Allegheny County judge ruled Tuesday that Pittsburgh’s firearms laws are “void and unenforceable” because Pennsylvania state law forbids municipalities from regulating guns.
