Chaska Ordinance violates U. S constitution

I know the City of Chaska has never really had an affinity for the US Constitution and it's probably too much to expect that it be adhered to do as more than a list of suggestive guidelines, However, I thought it worthwhile to point out that Article 1 section 5 of the Chaska City Ordinances violates the US Constitution. It reads It reads "It shall be unlawful for any person to use any rude, offensive, abusive, obscene language or gesture to any police officer, members of the Fire Department or any other officer or employee of the City while such person is performing in his official capacity as an officer or employee of the City."  'Id just like to remind my friends at the City Hall that they aren't running the Kremlin and although his attempts to institutionalize dissent could justify the thought, Scott Knight isn't the head of the KGB. This isn't the Soviet Union, folks. When a Chaska Officer stops me for no apparent reason and hollers from hundreds of yards away "Hey we wanna talk to you" and I respond "why? because I'm a black guy in America" "What are you gonna do? Shoot me?"They may not like that but it's still federally protected speech.The Supreme court ruled in Cohen V. California that offensive speech, even against agents of the government is protected. Justice Harlan wrote the majority opinion citing Justice Louis Brandeis's opinion in Whitney V. California that "To many, the immediate consequence of this freedom may often appear to be only verbal tumult, discord, and even offensive utterance, These are, however, within established limits, in truth necessary side effects of the broader enduring values which the process of open debate permits us to achieve. That the air may at times seem filled with verbal cacophony is, in this sense not a sign of weakness but of strength." Most people would probably consider adhering to constitutional principles as a more productive show of strength than tackling disabled people and other people's mother laws. but those are stories for another day, In conclusion, I was going to say that I have no intention of going to submit a formal request to the City of Chaska whenever I want to exercise my first amendment rights but then I remembered that Autistic people don't have any rights in Chaska..my bad.
