"John Carlos, who saluted Black Power with raised fists at 1968 Olympics, addresses Occupy Madison."

That and he's in town for the Wisconsin Book Festival with a book to promote.

After Carlos finished speaking to the group huddled together by the Occupy Madison camp in Veterans Park, listeners purchased the new book he co-wrote with sportswriter Dave Zirin, titled The John Carlos Story: The Sports Moment That Changed the World.

John Pope waited in a short line for Carlos to autograph his copy. "[Carlos] was at the top of his athletic prowess and instead of coming home as a hero, he came home as someone who was despised by a lot of people because he took a real serious stand against a lot of issues," he said.

And that's what it's all about, kids: taking a real serious stand against a lot of issues. And moving merchandise.
