Such a nice wise guy.

A Boston church official who claimed in an autobiography that he was a leg-breaker for reputed gangster James “Whitey” Bulger has pleaded not guilty to charges that he looted the church’s assets.

Edward MacKenzie Jr. is the former director of operations at the Boston Society of the New Jerusalem Church, whose members belong to the Swedenborgian denomination.

MacKenzie was arrested last week after a grand jury indicted him on charges including racketeering and extortion.
