Why did Madison police arrest a man for yelling about the badness of the Art Fair on the Square art?

After all the yelling that has gone on around the Wisconsin Capitol this year, I can't believe a man got arrested for loudly criticizing art! And our rag of a local paper, the Capitol Times, presents the story as if it's funny, as if the man — a homeless man — is some sort of clown and as if he had no right to express his opinions in public:

William Zamie, 62, no permanent address, was arrested on two counts of disorderly conduct and resisting arrest at about 3:12 p.m. Sunday on North Carroll Street on Capitol Square, Madison police said.

According to a police news release, a jewelry maker from Florida flagged down a police officer Sunday afternoon because Zamie was yelling derogatory remarks to potential customers after he had slept most of the day on the bench behind the jewelry maker's display.

"He said the artist 'was not selling real art' and the handmade jewelry was really 'mass-produced junk,'" said police spokesman Joel DeSpain.

The critic then entered the artist's tent to continue his harangue.

"He told a customer 'all these artists steal from each other and what you are buying isn't real art,'" DeSpain said.

Zamie's free speech rights do not depend on whether he was speaking the truth, but from what I saw at the art fair, he was.
