A Chicago administrative law officer fined Gay Liberation Network’s Andy Thayer $500, plus $40 court costs, for his role in last November’s anti-Proposition 8 march through Chicago’s Loop.

“Out of the 5,000 marchers, I was the only one charged with a violation of the ordinance,” Thayer said in the statement. “Even though the City produced no credible evidence in the trial that I incited the crowd to march, I was found guilty.”
