Robin Garrison, an off-duty 42-year-old firefighter, was walking in Berliner Park in Columbus, Ohio, in May when he saw a woman sunbathing topless under a tree.
He approached her and they started talking and getting comfortable, the woman smiling and resting her foot on his shoulder at one point.
Eventually, she asked to see Garrison's penis; he unzipped his pants and complied.
Seconds later, undercover police officers pulled up in a van and arrested Garrison; he was later charged with public indecency, a misdemeanor, based on video footage taken by cops who were targeting men having sex or masturbating in the park. While topless sunbathing is legal in the city's parks, exposing more than that is against the law.
