I live and commute in Chicago too, and am personally very happy that some cops are actually enforcing the law (though I'm sorry it did happen to you). Standard biker mentality here in the city is that traffic laws do not apply to them, which gives all bikers a bad name and make the streets more dangerous for everybody. I hope this becomes the norm, and they can put all that extra revenue into road improvements.

BTW, I feel the same way about traffic violations. I see at least one car breaking the law every day and can count on one hand the number of times I've seen someone pulled over in over 2 years.
