This may put your mind at ease or it may not. I worked for a large municipality whose police department issued tickets that charged "Disorderly Conduct." It was one of those charges that was issued to someone who the police want to charge but really have nothing to charge them with. Generally people were taken to the police station based on the charge and then 1) released immediately because the aim was just to get them to the station or 2) the charge was dismissed by the judge because the conduct was not very serious. Many times the charge was lodged because the officers realized they had not correctly followed protocol for more serious charges, e.g., public drunkenness or possession of marijuana. At any rate, I am not saying that it could never be serious however in most cases disorderly conduct indicates something that was not much to worry about.
