When Matthew Vilhauer was arrested last summer for riding his bicycle nude, one of the few things he was wearing was a helmet.But Vilhauer, 43, has agreed to pay a $50 fine for bicycling without a helmet, a civil infraction, to end his criminal case. Last month, a Clark County District Court jury voted five to one to find Vilhauer not guilty of indecent exposure, a misdemeanor that carries a maximum penalty of up to 90 days in jail and a $1,000 fine. With the deadlocked jury, the city of Vancouver was going to have to take the case to trial again. Court-appointed defense attorney Luka Vitasovic said Tuesday that Vilhauer has accepted the city’s offer of a civil infraction.While a helmet and shoes were the few things Vilhauer did have on that night, Vitasovic said it’s common practice to let someone take a lesser offense even if it doesn’t square with the facts.“There isn’t really a ticket that covers what he was doing,” Vitasovic said. And the infraction of cycling without a helmet was one of the cheapest infractions Vitasovic could find.Vitasovic said Vilhauer knew he’d have a decent shot at being acquitted if the city took the case to trial again, but was ready to end the case and move on. “I don’t think Matt was looking to be the poster boy for nude expression,” Vitasovic said.Naked expressionDuring the May 27 trial, jurors heard that Vilhauer had started the evening of June 18, 2009, with an art show at Angst Gallery in downtown Vancouver. There, he met with approximately two dozen cyclists who were out to celebrate with Todd Boulanger, a cycling advocate who’d recently left his position as a senior transportation planner for the city of Vancouver.
