Arcara presided over the trial of James Charles Kopp, who was convicted in 2003 for the 1998 sniper-style murder of Dr. Barnett Slepian, an American physician from Amherst, New York who performed abortions. Judge Arcara also presided over the internationally significant Robert Rhodes trial in 2005. Rhodes, a United States Customs and Border Protection Officer, was arrested and indicted for beating a Chinese National on the US-Canadian border in Niagara Falls, NY. The incident was addressed by then Secretary of State Colin Powell and Secretary of Homeland Security Thomas Ridge when the Chinese Foreign Minister accused the United States of human rights violations by Rhodes' actions. Rhodes was acquitted after a high profile trial in August 2005, presided over by Chief Judge Arcara. He assumed senior status on January 3, 2015.
