WI Statute 947.01: Disorderly Conduct. Whoever, in a public or private place, engages in violent, abusive, indecent, profane, boisterous, unreasonably loud, or otherwise disorderly conduct under circumstances in which the conduct tends to cause or provoke a disturbance is guilty of a Class B misdemeanor.
If you think that somehow, the "profane" part of the statute has been stricken because of a few nuisance settlements, you have another thing coming. You seem to think it is easy money suiing the cops and collecting nuisance money for arresting you. If you are a civil rights attorney, or a civil litigator, than I will defer to you. If not, I can assure you it isn't that easy. Are there cases where people have sued the cops, mostly for nuisance money? Apparently so. As for binding authority that makes this "settled law", not seeing it. Federal District court cases are not binding on other courts. Only Supreme Court decisions, and Circuit Court decisons but only for that circuit.
You mention two cases, one from the 6th circuit that has no citation (and in any case aren't binding on my state unless my circuit, the 7th agrees) and another case I recognize because it is really famous. In Cohen v. California the person using the f word was protesting the Vietnam war by wearing a T shirt that said F-ck the Draft, and got arrested for wearing it. He was not dropping f bombs on the cops, or on citizens passing him in the street. In that case, the Supreme Court said that it was clearly a case of political speech, and therefore protected. That is readily distinguished from the fool who drops f bombs in public places, in front of, or even in the direction of law enforcement.
I am not a civil rights lawyer, but I do criminal defense. If it were as easy as you think it is, the state would go broke handing out settlements to people who got arrested, but not charged. Actually the state is going broke, but it isn't because of civil rights lawsuits.
I never liked the Disorderly Conduct statute because it is both vague and overlybroad, and it gives cops and prosecutors too much discretion in deciding when, and against whom the charge can be brought. In my early years, I was constantly researching constitutional challenges to various parts (1st amendment, unconstitutionally vague, overlybroad, etc...) and in just about every case, I could find a state appellate case that shot down my defense. I once handled a case where my client was accused of writing something disturbing and offensive from his prison cell to someone. He was charged with disorderly conduct. I thought I had a defense based on Cohen and a few other cases, but as I researched the matter, there was a Wisconsin Supreme Court case right on point that said writing something offensive or profane could, under certain circumstances be considered "otherwise disorderly conduct".
