He took them off and kept running.
The Cincinnati police don't take too kindly to naked marathon running, apparently, and when they spotted Henderson (and his flying pig) they asked him to exit the race and get into a police car. He refused and continued running the race, at which point he was tased and arrested.
Afterward, Henderson tried to explain that what he didn't wasn't that crazy at all.
"This is something that happens and is tolerated in the running culture, along with runners who sometimes (urinate) or defecate during a race. Shouldn't that be considered indecent exposure, too, if what I did was indecent? In fact, running naked was encouraged in a marathon I ran in San Francisco, so I don't know why this was such a big deal."
Your first mistake, Brett, was taking the rules of the road in San Francisco and applying them to Cincinnati.
Henderson suffered burn injuries from the taser. He was arraigned today and said he planned to plead not guilty.
To make it worse he was not registered.
