In other words, if you ran stop sign, do you want to be a "constitutional martyr" and expose yourself to a cop's rage? Do you want to be detained for a day when you have a family and a job to go to, do you want your car towed, do you want random charges that are hard to defend slapped on you? Even if all charges are cleared by a judge, the amount of effort, time and money spent is too much for most people to handle. They'd rather fly under the radar, hopefully, the cops will catch the next guy...
Am I missing something? What else could a cop do that doesn't require documented evidence of wrongdoing? I suppose Chicago-level corruption could wreck your life, and if that's the environment you're in then it's probably best to keep your head down. And take part in local government, or consider moving.
Your tires could seem to be too bold, your windshield could have a crack, your turn light might not work properly. Then the cop start "smelling drugs" that are not there (police camera don't have smell detectors!). He might decide you need to a DUI test. You might be to close to a drug or prostitution area -- so just that lets them arrest you. He thinks your license if fake, so he detains you to take you to the station to establish your identity.
If he detains or arrests you, your car is towed. You don't show up for work, your family is worried about you. Basically, you cannot win. You can only lose after you encounter a cop.
I guess what I am saying is that I am disappointed at the legal system and the disproportional power the police can project. But aside from calling my congressman, I don't know if I'd want to try to be a "constitutional martyr" and get a cop angry at me...
