The Jacksonville Police and Fire Pension Fund approved a major pension-reform deal Friday morning, bringing some closure to years-long, frustrated efforts by the city's elected officials to reduce the burdensome costs of police and firefighter retirements. It is also a big win for Mayor Alvin Brown, who made pension-reform a top priority of his four years in office, and City Councilman Bill Gulliford, who stepped in late to negotiate a deal with the pension fund's executive director, John Keane, that was based on an earlier piece of reform legislation Brown pushed.
