Arthur is an alleged john, a man who patronizes prostitutes. After his arrest on September 5, 2008, a photograph of this 41-year-old appeared on the Web site of the Chicago Police Department. Arthur (not his real name) was far from the only person so branded on this Internet portal. Samuel, 59, and José, 34, (whose names were also changed to protect their privacy) were on this online pillory for a month after their September 5 arrests.
