When NATO came to Chicago along with what was supposed to be the G8 the entire city came to a dead stop and you could practically see a tumbleweed blow down Michigan avenue.
Since then the protesters have gone away. Here in Illinois we don't even try to reform unions or pensions like they do in Indiana (right to work laws), Wisconsin (the legislature leaves to avoid changes to public sector bargaining), and even MICHIGAN (attempting to pass right to work legislation). Thus, there is no need for the unions to come out in force, because no one thinks reform has a snowball's chance in hell.
That didn't stop these dopes from protesting during working hours in the loop. They probably weren't missing much work, anyways. At least the cops only seemed to spare a few guys on bicycles they didn't have to get out the riot gear and horses.
