Erick Williamson argued in court Friday that he should be free to go au naturel inside his home. But a judge agreed with prosecutors who argued Williamson's actions showed he intended to make himself seen.
Police said he made a point of making himself visible to a 7-year-old boy and his mother as they walked to school along a path outside Williamson's home in October.
Williamson received only a suspended jail sentence and no fine, but still intends to appeal.
Williamson's arrest received national attention and spurred debate about whether someone should be subject to arrest for exposure from inside his own home.
