In 2011, Will Walters was arrested for public nudity at the San Diego LGBT Pride celebration. He was wearing a kilt, open at the sides, over thong underwear -- an outfit less revealing than most bathing suits found at San Diego beaches, says his attorney, Chris Morris. Walters has sued the city in federal court, saying his arrest was a violation of the equal protection clause of the U.S. Constitution's Fourteenth Amendment. It shows the city has a double standard when it comes to nudity, says Morris -- one for LGBT people at Pride, one for everyone else. The city tried to have the case dismissed, but an appeals court ruled it could go to trial. Closing arguments are scheduled for Tuesday, and then eight jurors will make a judgment. Below, watch Walters and Morris talk about what's at stake.
