Disturbing the Peace is a Class III misdemeanor, which means that you are facing up to three months, a $500 fine or both. The minimum sentence is nothing. Hire a criminal defense attorney if possible or ask for a public defender. Your actual sentence (if convicted) will be based on your record and the specific facts of your case.
I am a licensed attorney in the state of Nebraska. However, the advice I give here is not to be taken as legal advice. It is merely my opinion based on the limited information given. In order to assure that your legal rights are being properly represented I would always recommend going in for a consultation with an attorney to explain your case in detail and answer any questions the attorney might have.
