An independent arbitrator has agreed that Quincy officials had the right to fire veteran police officer Joseph McGunigle, whose firearms permit had been revoked by the Police Department. In a decision issued last Tuesday, arbitrator Philip Dunn said that having a gun was a departmental standard that had been enforced for decades. The department and McGunigle have butted heads about a variety of issues since 2001. Most recently, McGunigle was the subject of neighborhood complaints in a dispute over traffic cones. Police Chief Paul Keenan subsequently revoked McGunigle’s firearms permit in March 2012, and the city terminated him in June. McGunigle appealed his firearms suspension in Quincy District Court, and the court upheld the city’s decision. McGunigle can appeal the arbitrator’s decision to Superior Court.
