CHICAGO — Protesters took their causes to the streets Thursday as an International Olympic Committee delegation arrived in Chicago — its first stop among four cities vying to host the 2016 Summer Olympics.

As committee members checked into the Fairmont Hotel and geared up for several days of meetings and bravado, Chicago police officers picketed City Hall, using the IOC visit to draw attention to a contract dispute, and the group “No Games Chicago” planned a downtown march and rally.

The opposition group, which believes the Games are bad for cities financially and can displace thousands of people, says money and energy directed at the Olympic movement should go toward schools, hospitals and transportation.

“The priorities in the city of Chicago, they’re putting on an Olympic games while the city is crumbling around us,” group member Bob Quellos said. “We’re being sold lies.”

Chicago is competing against Tokyo, Madrid and Rio de Janeiro to host the Games. The IOC’s inspection team, which also will meet with Chicago 2016 officials, is charged with grading the city’s bid.

Activities on their agenda include visits to proposed venues along Lake Michigan, where many sporting events would take place. The IOC is scheduled to make its decision in October.

Quellos’ group planned an evening protest outside Chicago’s Aon Building, where Chicago 2016 has met.

Earlier Thursday, organizers estimated about 3,000 Chicago police officers circled City Hall and chanted, objecting to recent actions in contract negotiations.

While union officials would not say they planned the protest to coincide with the IOC delegation’s arrival, the message was implied everywhere and officers participating said it helped the cause.

Several officers wore black T-shirts featuring white chalk outlines of bodies and “Chicago 2016” written underneath. Another had handcuffs in the shape of the Olympic rings. Other protesters criticized city officials; one sign read “Daley Unfair. No Games.”

The city’s police officers have worked without a contract since June 2007. Most recently, an offer that included pay raises was taken off the table, which infuriated many officers who came to the protest.

“We need to send a message that we’re frustrated with negotiations,” Fraternal Order of Police President Mark Donahue said.

Brenda Ellerson, a 24-year veteran of the police department, said it helped that members of the IOC were in town during the protest, particularly since officers would be relied upon if officials choose Chicago.

“We’re putting our lives on the line every day,” she said. “It’s just not fair. We know the economy is bad, but we still have to pay bills.”

Mayor Richard Daley spokesman Lance Lewis said the group has a right to protest, but referred all inquiries to Chicago police.

“We obviously honor the First Amendment right to exercise free speech,” Chicago police spokesman Roderick Drew said. “Both sides need to sit down and work on an agreement. And we would rather have the two parties sit down face to face than to target an unrelated event.”
