Duffey, who works as a production line operator at Corning Glass in Greencastle, Pa., also criticized Sager's emphasis on beautification projects.
"What's the sense of having a beautiful city if you're afraid to walk down the street?" he said.
Duffey said he would expand the police department's drug force and target small-time offenders, "not just the big dealer."
Duffey, a South Hagerstown High School graduate who spent six years in the Marine Corps and served in Vietnam, said he also would crack down on welfare abuse. Instead of hiring guards to patrol public housing, he said, money would be better spent to hire investigators to work second and third shifts to ferret out welfare cheats.
"Apparently, our mayor lives in his own little world," he said. "If he'd get out in our world, he'd find quite a bit."
Duffey said he is tired of paying so much of his income to the state and city governments. He vowed to freeze tax rates along with water and sewer fees while he worked to solve problems he said were caused by the current administration.
"This administration got us into this problem," he said.
Duffey said he figures the primary will be his greatest obstacle since he has a lot of Democratic friends. His campaign treasurer is a Democrat, he added.
Duffey worked for five years at W.D. Byron Tannery in Williamsport before being laid off just before announcing his candidacy for a seat on the Washington County Board of Commissioners in 1994.
Duffey ran unsuccessfully for the post. That race was marred by assault charges filed against him by a friend of his former wife. Duffey filed counter-charges against both women. The cases were placed on the inactive docket and dropped.
Duffey denied wrongdoing and said the incident was in the past.
"That's past history," he said. "There wasn't anything to it except to get a lot of bad publicity for me."
