West showed up with Russell Simmons as the protest headed into its fourth week. He toured the downtown plaza and shook hands with people, but did not perform like a few other artists have in recent days.
Mayor Bloomberg said on Monday that the protesters, who have established a headquarters in a plaza downtown, will be allowed to "express themselves" as long as they obey the laws.
Bloomberg commented in response to a question Monday at the Columbus Day Parade.
The mayor was asked how much longer he thinks the month-long protest will continue. Bloomberg said he had "no idea."
He added that if the protesters do something illegal "we're going to do what we're supposed to do — enforce the laws."
On Friday, a caller on Bloomberg's weekly radio show complained about "incivility" and noise at the protesters' encampment in Zuccotti Park.
Bloomberg replied that the city was trying to deal with such issues while protecting "everybody's rights."
