You have failed to ask a question.
You have the right of free speech, even if that speech is unwelcome. However, one cannot employ speech that causes danger to others or creates a public nuisance, generally.
Police often dislike being what they perceive to be disrespected in a public (can be worse in private) and it is relatively easy for them to slap you with a disorderly charge as it punishes the speaker immediately without causing the officer any additional work.
You will have the choice of whether to plead no contest to the charge or not guilty and your attorney will advise you accordingly.
If you suffered damages from the encounter (medical bills, permanent nerve damage, lost wages, pain and suffering, emotional distress, etc.), then you may have a suit against the city for excessive use of force. You may wish to prevail on the criminal charge to pursue the civil claim.
Either way, the lesson is to document what the police do when they're called, but don't try to shout them into being better public servants than they're inclined to be; it's a losing argument 99.99% of the time.
I agree with my colleague, and note that I already answered your reposted question at http://www.avvo.com/legal-answers/i-was-arrested-on-10-3-09-disorderly-conduct-intox-141197.html
which also did not ask a question. Consider re-posting again with a question. Good luck.
